Evoo would get you through your lease just fine.

The paranoia around here is unreal.

I've seen other people citing shear as a reason to use a heavier weight oil, especially in a hot climate like SoCal where ambient temperatures are high all year round.

There is a thread in the FA forum regarding how supposedly Xcess isn't that great for these motors and the Xclean is better. Some have said it's great for the EJ motors but not as good for the FA. I'm not enough of an oil nerd to really get into the nitty gritty of it. My UOA looks good and I have used this oil since the very first oil change in my car at 1K miles so until I have a good reason to switch it up, I'll continue to use it moving forward.
Oh i see. But like someone said, it's the DI that's the difference. I'm sure all these oils are fine, but DI engines are another animal.

Will probably just stick with x-clean since it's a 5w30 and that's what i'm using in the z06 anyway.

I will try it before winter hits and then one more oil change (around summer time), before i give this car back to the dealer.

But i'm curious on running the UOA on the magnatec though. I don't think i saw a UOA on it yet, at least for these cars.

I'm undecided if I want to go to Xclean or stick with Xcess. I will probably give it one more UOA to see if anything weird pops up.

Semi-related question regarding oil temperatures. I know modern synthetic oils are pretty robust and can easily handle temps of 250F+. That said, would a year-over-year increase in average oil temperatures be an indication of any mechanical issues, and is it something a UOA would even catch?

When I first got my car I rarely saw temperatures over 210 when just driving normally around town or at steady freeway speeds. Now it seems to hover more closely to 214-216 under same conditions and driving habits and same oil used since I first got the car. Obviously this is still well within the recommended operating temperature, but I'm more curious about the seemingly year over year average increase rather than the nominal temperature value itself. There are probably a million variables that can contribute to this i.e. formulation of oil itself, but just wondering if this can be a sign of something more serious.

Idk, i would just change to x-clean since it's a 5w30. x-cess is 5w40 right?

I don't like storing different brands of oils so i try to find something good, then just buy a bulk so i can use it on all my cars. That's why i went with motul x-clean. Plus it's dexos approved too so good for my z06. I'll be getting a UOA for that before winter.

Magnatec is coming out in about a month, or just before winter, even though i would have only put like 2200 miles on the oil lol, i'll change it anyway and get a UOA on that. Then x-clean is then going in there for the winter.

Btw, yes there can be differences in temperate given the oil. At least from what i experienced.

I've done about 3 oil changes with PUP. and Everytime I fill up with gas, I check the oil. It comes out golden everytime. I'm surprised with the copper issues that people are mentioning. Does anyone have a recent UOA of PUP 5W-30?

From my very limited knowledge, I would say that the age of the oil is a major factor when considering temp. The oil loses its viscosity and shears over time. The oil thins and becomes less effective at lubricating and keeping your engine cool because friction produces heat. That's just my guess. I'm pretty sure someone with more knowledge could answer your question better. Hope that helps.
