Which oil are you using?

[mrt6644]

Sorry to prolong this but here's the final line for me:
If cost were no issue, what would you use? Rotella dino oil(with our without additives) or Mobil 1 15-50?

And if you use Mobil1 15-50, would you still need additives?

Our Walmart carries this SF-rated high-zinc motor oil for $2.67/qt. I run it in my ATV and FJ40 and 62. It's US-made and legit.

 

[Cruiserdrew]

Contains "at least" 1100 ppm zinc. Don't they know? A lot of HD oils contain that much in the most up to date formulations, and I thought above 1200 was the desirable range for our vehicles.

This has become a swamp. Lots of additive voodoo. The Mobil 1 15w-50 is looking like the solid choice to me.

What is the zinc load in the Mobil1?

Jim-The mobil1 chart has been updated as of May 2014. They even come out and state it's good for flat tappet applications.

It depends on which of their oils you're using. I did a quick google search and found a similar question asked on a Mobile 1 site. Here is the link:

And here is a table showing the level of zinc and other additives in each of their oils.

So... "all things being equal" otherwise and given EQUAL Phos and ZN levels is it true that synthetic is better that dino oil?... is that your question?

Diesel oils may, but gas engine SN-rated car-type oils don't. I won't pay $7.50/qt. for racing oil, no matter what - with 2 Land Cruisers and 4 other vehicles. For actual tested zinc content, refer to: http://www.pqiamerica.com/samplesummaryHDEO2.htm

I agree that diesel oils contain slightly higher zinc levels.

And the winner is.... Chevron Delo 400LE SAE 15W-40

For me the point is finding an oil where I don't have to add anything. Maybe Im naive, but if you have to add extras, maybe its not the right choice?

I've been using Mobil 1 Turbo Diesel Truck oil, but switched to dino Rotella recently. So far they are both similar from what ignorant perspective I can tell.

The 40/2F gets Castrol, whatever is appropriate for the season.

 

[Spike Strip]

I don't trust that PQI report. I've never seen a VOA on DELO LE above 1100 PPM Zinc. There are two kinds of DELO 400: LE and Multigrade, both 15w-40, but the multigrade consistently shows high zinc loads on VOAs and is made for pre-2007 engines. But it's hard to find unless you have a trucking place near you. I think they switched the two.

 

[Benjaman]

Not true! Times are changing, and so are cars. Oil companies won't continue to make products for cars that have become the minority.

So we need to make adjustments, such as adding the needed ZDDF for older designed engines.

There is a recent oil analysis of unused Chevron DeloLE 15w-40 on Bobistheoilguy-Zinc was measured at 1244. That's likely sufficient and easy to buy anywhere. As a default it would be good. We are talking 2F tractor motors here, not race motors with high spring pressures in the valve springs.

While using SN GF4 oils might be potentially harmful to our motors over tenthousands of miles, I think the DeloLE would give perfectly adequate service right out of the jug. I'll stick with Mobil1 since I've standardized all my cars on that. My two 2Fs and one 3FE will continue to get the 15w-50 until Mobil changes the formulation.

I did see DeloLE 5W-40 Synthetic the other day at Orielly mismarked at $11.99/gal and bought 2 gallons. My FJ40 is going to be the test mule.


On another tangent, my 80's last change was the Mobil1 European Car Formula 0w-40. I've got 4000 miles on that change and can't even see on the dipstick that any has been used. It's volatility must be extremely low. Oil pressure is the same as it is with the 15w-50.

 

[mrt6644]

I took the easy way out. I went to Walmart and bought Mobil 1 15W-50. As much as I like the idea of Rotella, there are too many people that say it isn't good enough on its own. That doesn't cut it for me.
Mobil 1 has a zinc ppm of 1300
I will also add that I know pretty much nothing about oil and what is required. I am not countering anything that is said here, but trying to get a summary of opinions. I do believe there are a lot of knowledgeable people here and I aint one of them.
Im not opposed to Rotella, but given what I have read, Mobil1 may be better. And at Walmart prices, Mobil1 isn't really more expensive anyway.

 

[Lasse]

I have access to quality oil and grease for a good price trough my brothers workplace.
I use fully synthetic 5w-50 Dynocat oil in both my engines. One 2H diesel and one 12H-T diesel.
I pay about 10$ a litre

Neither of the engines seals seems to have any problem with this oil, I change every 5.000km together with filter, maybe a little often, but better play it safe

 

[Granite Grinder]

Dang Lasse, those are expensive oil changes
I'm using Quaker State Enhanced Durability synthetic blend, 5W-20

 

[Lasse]

It isn't that expensive really, a good Mobile 1 oil cost from 20$ a litre and up. That is expensive!
OEM filter is another 50$ at the stealership, cost to take care of these nice trucks, but it is also worth it
If I opted to cheap out I could had bought some cheap low quality 10w-30 mineral oil for about 6$ litre in 10L cans.

I'm using Quaker State Enhanced Durability synthetic blend, 5W-20

With such a low warm viscosity rating, don't you have trouble with well enough lubrication at engine running temperatures?
I know modern diesel engines starts to use long durability 0w-30 oil, but those engines also runs a lot more efficient and doesn't produce the same amount of heat. The 2AD-FHV (2.2L diesel) in my brothers Avensis uses 0w-30 Toyota oil at each change.

 

[Spike Strip]

There are so many stinking posts in this stinking thread that the point has been lost that low zinc oils, even at 1300 PPM, may be fine out of the jug, but as zddp gets consumed, it drops below 1200 ppm very quickly, which is what I've read numerous times as the threshold level for these kinds of engines. So unless you're changing your (insert oil of choice at around 1300 ppm here) at 1500 miles, it's not gonna adequately protect your motor. That's why the recommended level is 1700 ppm , so with 3k-5000 mile OCIs you're staying within range over the service life of the oil.
