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.JLF said:Why not Valvoline for DI engines?
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 fuelJLF said: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.

I take it you do not read information provided huh.....wbassnp007 said: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 your trying to be some kind of smart ass??? all I asked was what someones opinion was I dont need brought to task because I didnt click on your link..But thanks for the info2010BlkGraniteNox said: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.wbassnp007 said:How does Amsoil compare with the brand you recommend?
