Chris-St Louis said:Interesting list. I havent look at it too hard, but noticed the oils that are avalible in teh US, seems to be mostly 15-40,wish requires a sheer rating of at least 3.5. Curious about the others.
The Sierra does need at least a 6049 oil, no biggie really...most of them are cheap and readily avalible.

The Sierra calls for 5W-30 ; every oil I'd consider using is on GM's list for that weight... (Castrol GTX, Mobil 1, Havoline...). Good to go then, just keep on, as I was, for it.
(I don't see Rotella on the list?)
For the Series, since it calls for 10W-40 or 20W-50, but the American oil market has moved away from those weights, would I be better off pulling back to 10W-30? I'd rather run something heavier, given the age/mileage. I think I'm leaning towards the Rotella 15W-40.
Yep, after I have gone through what I've got on hand of 20W-50, I'll migrate to the 15W-40.
Done.

Rotella isnt the best choice for every engine. There is no one size fits all anymore.
I like it for Rover engines because Rover engines were designed in the day of way different oil, where sheer wear coudl be made up with ZDDP. In fact, in older engines, I almost always recommend a oil with a 3.5 or better rating...Either a 15-40 or a ACEA A3/b3 oil. The newer stuff that HAS a current manufacture spec, I default to that.
Keep in mind, a 5-30 isnt always half as thick at 32 degrees as a 10-30. Its more complex then that.
A 10-30 in your rover woudlnt be a good choice. 15-40 or a ACEA A3/B3 might be overkill, but it will do the job. 10-40 is a Base 1 stock...Cheap.. I cannot think of a application that current 10-40 meets the grade.

Chris,
What is the best choice for my new beater, a 2000 camry 4 banger?
168K, drives like a champ.

I run rotella t 15w40 triple protection during the summer, but still go back to a thinner oil in winter. truck sits outside during the winter, below freezing, is 15w40 still appropriate in a cold climate (cleveland ohio)?
Yes. If you really are worried, Use a Mobil 1 0-40, or castrols syntec 5?-40.
Read the back of the bottle, make sure it is ACEA A3/B3 rated. Then you get the same sheer rating as a 15-40 provides

Chris-St Louis said:And, now the answers!
1 is d (Castrol & Valvoline do not have any products in the USA that meet the GM 4718M or Honda HTO-06 requirements for cars sold in America. There is only 1 Mobil 1 product that meets those ratings, and the listed one is the wrong one)
2 is d (none of the commonly available 5W-30 products from Mobil, Castrol or Penzoil meet BMW minimum requirements)
3 is a (SAE viscosity requirements are very "wide" the listed ACEA rating assures a much thicker 0W-30 product at high temperature than a 10W-40)
4 is a (Hot Rodders recomend "diesel 15W-40" only because they don't understand, or even acknowledge the ACEA ratings)
5 is c
Chris, this is good info I guess, but it really is stupid that none of the oils that actually meet specs required by the engines sold in the states, are actually abailable in the states! Call around to various dealerships, they all use readily available off the shelf stuff that according to you does not measure up to the requirements of the engines they are being poured into!

They are, but you have to hunt. Some of the Super exotics (Ferrari,Lambo,Etc) take a ACEA E3/B3 oil in like 5w-60.... Thats a toughie. But, most cars require hunting..
For example I was at Parts Plus here in St Louis, and they had GREAT oils. Even had the o-20 the Hippie Prius owners begged for mobil to bring back. They had a oil there to meet every spec I coudl think of.
Compare that with Carquest, They did not have ONE ACEA rated oil.
It would be nice if part suplliers knew about this, so they coudl stock the proper oil for the job, and be able to recommendd it to their customers. Sadly, Dealer service managers are motived by money, then their customers best interests many times. And, they buy whatever is on sale. The manufacture tells them, adn makes it avalible, but theres not as much money in that.
The tide is changing though.
Since I've got a barrel of Rotella 15W40, I'm throwing it in the new Disco and the Camry. I don't have time to shop all over for these specs, what will it hurt on the Camry.
I'm assuming its the current 350Z, which Nissan calls for a ILSAC GF2/GF3 in 5-30 year round. GF-3 is the EXACT same thing as GM 6049M, so it's easy to get.
Again, not ALL oils meet that spec, but many do. THe list is in this thread.
Some extra credit reading on ILSAC ratings, A little dated, but good info.

Chris, you mentioned that you wouldn't recommend Rotella in colder climates. On an esp. cold day here in GA, I noticed the oil light stayed on a few seconds longer on startup.
So, how cold is too cold to run Rotella and what's the next best option?
Thanks for all your help and knowledge!!

I woudlnt recommend it where it gets so cold that the engine cant spin fast enough (50rpm) to let the ecu know its starting. How cold that is.....Hard to say.
I would say, price not being a factor Mobil one 0-40 (Confirm it says acea a3/b3 on the bottle is a great choice yearround. The sheer rating is simialr, and cold flow is great.

I used M1 0w040 in my Audi because of the strict VW/Audi requirements. That oil is expensive and extremely thin....pours in like water.
I use rotella 5w-40 synthetic. Its has a shear of over 4 point something. Plus it has a high zinc rating, possibly higher than that 0w-40, not sure though.

It's a pain in the ass finding Mobil1 0W40 down here. They have a shitload of the Diesel Engine 5W40, but after looking at 5 places, none of them have it.
Oh, but the Kwik Lube down here will do an oil change with Mobil1 0W40 for $65. Fucking price gougers.

Of course. It has a GREAT cold pour rate, and it acts like a 40 Weight at high temps. Being ACEA rated, it has to.
Its a great choice for Flat lifters. Check th espec sheet, and compare it to others.
