Does anybody have an opinion of Valvoline's Synthetic motor oil 300,000 mile engine warranty?

No. But Valvoline would not be the best choice for our Direct Injection Motors. Probably Pennzoil because it will clean the best. There are many posts on this subject and also go to BITOG and read forever about oil

Why not Valvoline for DI engines?

Its not that it doesnt work...Valvoline would work just fine in all honesty....But DI engines run dirty, they have carbon build-up due to design of engine, and the atmoized fuel gets in the oil (fuel dilution similar to diesel technology). Oils that clean are considered better, Pensoil is one that is considered nice for DI engines because of this. It has an extremely hgih content of cleaning agents vs others. In the end run w/e you wish, its what you fill comfortable with. In all my DI engines (this is my 4th) I've always used Platinum, and just switched to Ultra for the Nox. I perfer to try to clean the engine best I can, coming from VW family, we had numerous issues of build-up in those engines.

DI is not the same as regular FI engines.......Its going to take time before others realize this, Mechanics have little knowledge on it (your average), this is just the 3rd engine to go DI from GM, so your dealers are finally starting to see them. Reason alot of the issues complained about on here, are actually just normal for DI....And people wonder why GM doesnt go mass market with diesel technology :)

Thanks, that must be the reason the oil was so black on the first oil change. I changed it at 2978 miles and it looked like very thin black paint. Maybe I'll try the pennzoil on the next oil change.

So a Synthetic Oil with detergants is better for the engine because it runs cleaner. What about viscosity and friction reduction of moving parts as this relates to engine longevity and wear?

Black is the norm on these :).....I did a UOA on Mobil 1 in my Cobalt SS (2.0 SIDI Turbo)....After 1k miles it was sheared from a 30weight oil to 20weight because of fuel dultion. This was the factory fill, the LNF was factory filled with Mobil 1 Full Syn 5W-30. I'm certainly not an engine designer, but to me an oil that in 1k miles becomes grades lower is not good :). SIDI Turbos where really hard on the engine, these should not be that bad....no rush of 24psi and loads of fuel :p

This just has Platinum and not Ultra compared to some other oils. Moly is typically used for friction reduction. The vis @ 210 is what I would be more concerned about will edit when I find the ultra voa, reason I switched, I was going to stick with what I liked (and it was cheaper than Mobil 1)

Oh and BTW you will drive yourself crazy if you start looking around at this stuff.....In the end in all HONESTY any good quality oil/filer will work. If you wish to extend your oil changes past the 3-5k mark, then go to Syn. If your a nut job, who doesnt mind spending around 27.00 an oil change, then do as I do :)

Castrol Edge is a synthetic motor oil which claims 8 times more wear protection than Mobil 1. Has anybody had empirical experience with this product or is it too new??

I take it you do not read information provided huh.....

Castrol Syntec and Castrol Edge VOA's where posted in the link I provided.

Its not new, Edge is full synthetic while syntec is not, its hydrocracked oil. In Europe they have tougher standards, oils that are not true synthetic's cannot advertise as such, Edge is the European Castrol formula as I understand it. Its really no big deal though...just a better forumla

I mean seriously how often do you change your oil? If you do it every 5k just stick w/ anything that you like, it will all work as I have said before. If you wish to run extended oil life, follow GM's recommended oil list, if you wish to go past that, into the 15-25k range, use the expensive stuff. But if your not changing at those high intervals, you are just wasting you money. VOA's do not list everything the oil does, but I like to see how much of certain elements are used because those elements are put in for a reason, either anti-wear or cleaning agents.

From what I've experienced, the only way to go. They pioneered synthetic oil, I think they started sometime in the early 70's. All these other companies are finally catching on how goos synthetics are. I've been using Amsoil since 1985 in all my vehicles, never a problem....change it once a year (or 25000 miles) Amsoil filter every 6 months. Sure Amsoil isn't cheap, but you will save money in the long run.

Does Amsoil meet the GM criteria? I think that would be the 6094. Also from what I have read the best cleaning oil is the Pennzoil (Platinum and Ultra) I am using the Ultra and when I get to about 7000 miles will send off for an oil analysis. I put the Pennzoil in at 2700 miles .

So Amsoil meets the GM specs. That's very good. I guess we will not know whether Pennzoil Ultra cleans better than the Amsoil until results are posted. That is an issue that should and will be discussed on other posts and forums. Both oils I believe would perform better that the Valvoline, especially on our 4-cyl DIC engines. For further info one should check out the BITOG website for all the info you need to know about oil and filters.
