Anyone tried Royal Purple

[NYCTRD]

All I was saying was if you use an improper lubricant, they can void the warranty repair on the unit affected. I didn't mean void the entire warranty!

I actually had the dealership do the first rear diff oil change so they'd see the dark black oem oil and special metal shaving additives.

I brought the royal purple and the tech wanted to make sure it was approved by toyota before they used it (translation: cover thy assse)

When they saw how black (translated: overheated) the diff oil was and the metal shavings, they didn't charge me labor (I was there getting one of my first year free oil changes).

Royal Purple (3 quarts) $12

Dealer documenting crappy rear end: priceless

BTW-I'm aware of the MARKETING reasons behind the name & colour "royal purple" (and it's medieval origins), I just wanted to know if a beneficial additive caused the purple colour, or if it's food colouring!

I saw this thread and said to myself, "self, if REKCUT isn't contributing to this discussion then self should shoot self in the head"!!

I know Rekcut uses it, and based off what he told (educated may be a better verb) me, and a little research on my own it was a very very simple decision to change to RP. Since you can find RP in every stealership parts shop, and everyone one of your service advisers promote it...then I think its safe to assume you will not void warranty. Just mind the manual on how often you should change. Also my understanding is that the 08 come with this fluid already in it...the 07's did not. I noticed better performance all around, and I changed out front and rear diffs, transfer case, and Man Trans. gonna use it on the next oil changed as well. Gear oil, like gas, or any other fluid is the life blood of your truck. Spend the few extra dollars, your truck will last longer and thank you for it (i have actually heard my truck "thank" me).

was at the dealership the other day and ol' boy brough his 97LC for an oil change. Showed me the odometer....freakin 471k miles on it. he uses RP...I would have to say he got his money worth all around, 30 times over!! i love seeing stuff like that, and he takes it offroad.

also those worried about the price, and we all know the dealership charges more than anywhere else. just give them your TLCA member number which should be good for 30% off the price. This makes it cheaper than if you went to autozone or pepboys or whatever local shop you have in town to get the stuff. also don't know if its a coinicidence, but the dealershop has the pointed top bottle...all the other places have the reg bottle. pointed=easer to get into small places and flip the bottle. like i said, just what i saw. im sure toyota is not the only place that has that style bottle.

VIVA ROYAL PURPLE..make the switch and thank yourself that you did.

I've been using synthetics exclusively since 1984. I've used Castrol (when it first came out), Mobil1 for most of that time, Redline and now Amsoil synthetics.

Never had any leaks in any of the vehicles. Even changed one over at 109,000 miles.

I totally disagree that there is no benefit to changing over an older vehicle that has been on a steady diet of dino for years to synthetic.

The synthetic will clean the engine out very well. It will free up the rings if they are stuck and restore some compression and even reduce oil consumption if that is an issue. It will let the engine handle very cold temps and very high temps far better than dino.

I've never seen a measurable increase in mpg on any vehicle that I run synthetic. Will it increase HP/TQ, I don't know and I don't care. I use synthetics for the reasons I stated above and use them in everything (diesel tractors, lawn mowers, riders and push, chippers, shredders, snowblowers, etc... I mean everything.) I just changed over a 16 year old lawn mower to synthetic. It will clean the rings and bring back the compression, reduce oil use and make it easier to start.

So, for the reasons I stated above. I must disagree, based on 24 years of real world experience in varying climates in various pieces of equipment with various oils.

yeah their intelligence and curiosity along with prey drive make them difficult for those that dont understand them or have the knowledge to train them and handle them properly. my wife has a sweet bullmastiff as house dog but looking forward to getting another shorthair or maybe a pudelpointer and getting back into hunting more like I used to before I retired from military and started my second career. LOL

good luck....

I bet it's grape juice

I was at a truck show this weekend and stumbled onto a Royal Purple booth. I started talking to the guy, and man did he like to talk. He explained why Toyota picked them to for their dealership parts stores. Evidently it went back from all their work on aircraft, nascar, indy and dragster engines. There were a lot more but I forgot. He also stressed that it is a true sythetic not a mix. Said most moble 1's are true, but some are mixes his point was to make sure. He didn't knock any of them, and said M1 was very good...but obv more expensive. best guess is you are helping pay for their advertisements?!!?

THE most interesting part of his spill didn't have to do with RP, but with "TRUFILTER". Have you guys heard of these, and are they any good? Its the filter they plug, and its a one time cleanable filter. Take if off and clean it whenever you want. He also said the filter goes with you on each car purchase. Call trufilter up and let them know what you bought and they will send you the new seal that fits your new vehicle. Any thoughts?

[NoHandleBars]

Lol I was just argueing with someone over Trufilter. It's a stainless-steel mesh media cleanable filter. Seems cool, but there isn't much data on how it compares to higher-end synthetic replaceable filters, it only compares itself against the "norm" aka Paper Filters. Once the proven data is out, I'll prob buy one. I'm suprised K&N isn't making one...it seems like something they would jump at.

i thought the same thing, i looked for it on k&n. if it was all that great they would have jumped on it. time will tell.

[peepers]

how about each of you running a different oil takes a sample at the same mile interval and sends it to these guys: Blackstone Laboratories - Gas Engines

sure you can say the miles on the vehicle, the driving style etc etc can all contribute but it would sure be more "scientific" than the banter going on here... maybe there will even be a post with out the caps lock on?

[FirstToy]

plenty of freedom to post what you want but no personal attacks are allowed here. let's keep this a technical discussion to benefit all the FJC members. thanks guys and please continue w/ the RP discussion

Just a suggestion!

BTW-IS it grapejuice??

I agree to an extent, but don't know if that smilie is meant to be offensive...heck the cartoon has a giant smile on his/her face!!

back to royal purple. i have always paid attention to where my engine heats up to. to bad i don't know the exact temp of the engine...but over the last week i have seen a dramatic drop in engine temp. you all seeing the same thing running synthetics?

[Toledo FJ]

Maybe K&N isn't jumping on the permanent filters because they make more money selling disposable filters. Or maybe the SS filters aren't as good yet, so they are waiting for them to improve. I'm the guy N-H-B was "arguing" with about the trufilter. I've had mine in for a about 12,000 mi. and I'm still not sure what I think. The trufilter is cool looking, and extremely easy to service and clean, but I just don't know if it provides superior filtration to the High end synthetic (cellulose, fiberglass, or polypro) filters. As NHB stated, the only data I can find is in comparison to the standard paper filters. All the other "data" seems to have little backing either for or against these filters.

I think Trufilter would really be the shizzle if they offered the option of disposable Cellulose/glass filter inserts as an option to the SS filter media. Or even a synthetic insert to use WITH the stainless steel screen. Now that would be sweet. I think I'm gonna design it and sell it and make a billion bucks... i wish.

At this point I don't know what to do regarding filtration. Perhaps another sweet option would be to run a dual filter setup using the Stainless Steel filter AND a high end synthetic.

sounds like you have done your research...I say go for the billion!

My point was high-end long-term oil filter makers WOULD jump on the SS wagon if they saw a nice market for it. Each SS filter sold would equal about (average) 150 regular K&N filters. A car uses 150 K&N filters in what...? 750,000 miles if you change the filter out at 5k. I think K&N would rather get that payment right then and there, then wait 750k . Dual filters are too much of a pain to hook up.

[Toledo FJ]

IMO nothing is too much trouble to set up. Get some friends together and get your wrench on! In fact this weekend there is gonna be a big work day at Lance's (excriment on the blue forum) house. Anyone in the Toledo/ Bowling Green, or anywhere in SE michigan or NW ohio is welcome to come for a day of mods, food, fun, and friends. PM me if you are interested and want directions. It should be a good turn out!

Are you talking about the cheapest K&N filters? I haven't seen $1 filters and certainly wouldn't run one if I did. How much do the filters you run cost. When I ran high end synthetics, they were between $10 and $15 a pop. I change my oil every 3,000 mi (I know this isn't necessary, but the more you change the better), so it only takes about 30,000 to 50,000 to pay for the TruFilter to pay for itself, and double that mileage for the PurePower to do the same.

Peepers,
Thanks for the link to the lab. I'm gonna do exactly what you suggest to see if I can get some real data.

Cheapest = 10-15$ that's how I did the sum up and = 750k miles....I did the math there, just didn't post it piece by piece.

[Toledo FJ]

I don't understand how you possibly arrive at 750,000 miles based on $10 dollars for the cheapest filter. If you are changing you oil every 5,000 miles, you will need 15 oil changes to equal the cost of the TruFilter ($10x15=$150). If it took 150 throw away filters to pay for the TruFilter, it would retail for $1,500. You are off by an order of magnitude.

So at $10 dollars per filter, and 5,000 mile intervals, the filter pays for itself in 75,000 miles.... not 750,000 miles.

It seems like the more I try to find out about filtering efficiency of ANY filter, not just SS media, the less I know. I've found seemingly reputable sources praising SS filters (Numerous hot rod and motorcycle mags) and others trashing them. Nobody, however, provides solid data that I can find. Also, it seems that different filters use different testing standards, so it is really hard to know what you are comparing. I'm waiting for a call back at the moment from the tech departments of both TruFilter and Pure Power. I'll get to the bottom of all this eventually, but it is taking some serious legwork.

Mistype. added an extra 0. Regardless, my point still stands. I'm done with this argument, as I could really care less. If these filters were all the "hype" bigger manufacturers would be getting into them, ESPECIALLY the company's that have been making filters for over fifty years and so on. But whatever, I'm done.

[Toledo FJ]

Well, I won't direct the conversation toward you anymore as you seem to be irritated for whatever reason. I don't buy your assumption that if they were great, bigger companies would be all over them. In fact the contrary is usually true. In my experience small companies almost always make superior products to the giants (of course this is a generalization and not absolute).

I have no interest in anything other than protecting my engine, and I'm in no way invested in wanting Stainless Steel filters to outperform synthetics. If I find that the TruFilter doesn't provide adequate filtration, It will be off the engine immediately and I'll go back to the quality synthetic filters I ran previously.

So, to anyone who is interested in getting to the bottom of all of this filter business...

I just got off the phone with my local performance shop and they were not familiar enough with Stainless filter screens to offer an opinion. They suggested having an oil analysis done in a lab. I will do an oil change, and run the TruFilter for 1,000 miles and then do the same with the K&N or Mobile 1. Send it in and we should have some first hand info. Of course I'll test both under similar driving conditions. 1000 miles in the city is gonna be different than 1,000 highway miles. So, It will take some time to get an answer, but at least I'll have some proof one way or another. If I run into any good info in the meantime, I'll post it up in the "oil filter.... which one?" thread.

[FirstToy]

This is enough. Please discuss the products based on technical merits or relay your opinions in a way that is respectful to each other and all the readers.

If it continues, I will simply clean up all the trash talk. This type of thing does nothing but clog up things for people searching for real information and opinions
