Engine Oil survey

[DTAYLOR]

Ok, let's pretend we know what we know now and can roll the clock back to 1997. We're going to buy a brand new 80 with zero miles on the clock. We know we want to max protect the engine for expidition use and hot conditions of North Texas. (home of three weeks of 100 plus days in a row)

Over kill is the rule of the day. (or else we would be driving jeeps)

What engine oil will we use? Synthetic most likely, but what flavor???

Let me hear from ya.

Did you read the Oil FAQ? 0 miles or 100K miles shouldn't make a difference.

I'd be running the same stuff as I currently am now (83k miles).
0w30 German Castrol Syntec

It's explained here at Bob is the Oil Guy:

I just put in 7.6 quarts of my flavor in this morning...Mobil 1 5w30 Truck & SUV. I have 99,504 on the clock on my 97' LX. She was very happy this morning. She also got a new OEM air filter and a big ol' OEM oil filter....thanks to CDan of course. Oh yeah, she would get the same exact love back then too, if I only had her then. It is ok though she appreciates me more since she had a PO.

valvoline maxlife 10-40 but when it cools of i use 10-30. when i last sent my oil to blackstone they said the oil was still good and the recomended adding 1000 miles to my service interval

Um, not to nitpick, but you would not want maxlife in zero mileage engines; it is intended for high mileage engines and will work to sorta swell seals, add some extra wear additives, etc.

I would use Mobil 1 5w40, if i could find it, i wish that they would stop screwing around and re - re - release it. If I could not find the 5w40, I'd use the 0w40. HTH.

mobil 1 5-30 for now, but in the future might run 0-40

Another awesome choice, just remember that M1 tend to be "thinner than" equivalent dino oils, perhaps the perfect choice for a fresh motor with super tight tolerances. I'd still swap to at least 0w40 within the first thirty thousands miles. Again, that 5w40 was so sweet, the perfect "blend" for our rigs I reckon. HTH.

I'm afraid to post because i'll prolly get grilled. I use that high mileage Valvoline 75k mile Maxlife 5w-30

The 5w-40 is back. I saw it at a local store recently, just keep looking. It is now called Mobil 1 Turbo Diesel Truck 5w-40.

Suweeeet! My favorite ever, ever, ever!!!

Please specify organic or synthetic...

My cruisers both get Valvoline 5w30 dino juice. When I run out of that in another round of oil changes I'll likely switch them to 10w40 based on recomendations here for next summer. I know a lot of you are using synthetics to get more distance between changes. I'd rather change it more frequently and get any oil pan particulates out on a more frequent basis. I'm using Wix 51515 filters and changing about every 3K miles or when the seasons change, whichever comes first.

In my 2001 Z28 I use synthetic Valvoline 5w30. It gets changed on the same schedule. It has a very tiny filter and a flat oil pan. I'm not comfortable going with GM's 10,000 mile recomended change frequency so I do twice a year on it and only put 5,000 miles a year on the clock.

I've been told I change the oil too much. I think it is cheap engine insurance.

YMMV

What do you recommed for my rig with 135K with SC? I am in Central Cost California, and the weather here is pretty mild here all season. I don't tow. Let me know.

sory i missed the "time travel" part

You know, I'm not the expert, Cary really is, but, I'd go with the Mobil 1 5w40. Is it leaking anywhere at all?

I recommend reading the faq as it covers it.

Anyone ever used that Royal Purple?

I saw something on TV about it. Sounded good, but who really knows.

Since this engine is a fresh overhaul, and I have designs on putting another 200 to 300 k on the rig, I need to protect it as best I can.

I want to go synthetic, and Mobile 1 comes to mind. I'm sure there are many other good ones out there.

 

[Cruiserdrew]

I think Royal Purple is a scam. I mean, it's OK, but nothing special at a premium price.

Mobil 1 is the stuff. It is proven, and backed by a team of engineers that tiny companies like RP or Amsoil can only dream about. Check out all the Mobil1 oil analysis that has been posted here on this site. It's available anytime of the day or night in every city in the USA, and can often be found on special. It is the one thing that takes me into Wal-Mart even though I have to shower immediately afterward.

I personally use 15w-50 in the summer (no flames please) and 0w-40 in the winter. I get the "big" traditional Land Cruiser filters from our friend at American Toyota.

If I had a new engine (in my dreams) I would run a couple of short changes with Delo 15w-40 with drains at 100, 500, and 1000, then switch immediately to Mobil1 0w-40 and run that for the life of the motor.

Mobil 1 is factory fill in:

* Acura RDX
* Aston Martin
* Bentley Amage and Bentley GT
* Cadillac CTS, CTS-V, XLR, XLR-V, SRX and STS and STS-V

* Viper SRT-10

High praise that speaks louder than words.



Keep in mind, in UOA's there is no widely available oil that produces as consistantly good results as M1. When pushed to their mileage limits (15k miles plus) M1 performed better than Amsoil in a back to back test of the same car. Royal Purple consistantly shears down. Redline does great in race motors under extreme conditions, but consistantly falls down in extended interval oil changes (but sometimes does incredibly).

The only other oil that is consistantly as good is German Castrol, which is one grade of Castrol Syntec (0w-30) that is made in Germany. I don't recommend it for the sole reason that availability is spotty, and Castrol has two 0w-30 oils in the US, so the buyer has to be careful and check each bottle to make sure they only get the superior made in Germany stuff.
