Just a quick note: I am running EcoPower 10W30. It's recycled oil, made by SafetyKleen.

The reason I am using it? I have seen two excellent 7K mile UOAs on this oil at Terry Dyson's website.

I can't post the numbers because of a non-disclosure agreement, but the oil got some great wear results with improved oxidation and nitration (i.e. combustion efficiency) despite significant fuel dilution.

I'm only planning on running it 3K miles (from 3K to 6K) before changing it out, but I will post my results here.

Here is my recent oil analysis on Pennzoil Ultra 5W-30 for 4000 miles. Plan on running it again for 5000 and working up to 7500 if things still look this good.

I didn't see any 5w-30, but if that isn't an issue for you(warranty), contact them and ask about the suitability of the oils. I didn't see any claims that the oil was specifically for car application (excluding mention of API SM), where the did list the ATV/Motorcycle applications.

some people like mobil 1 some people say it's bad for our engine.. This a BIG debate. Plenty of threads on this subject I recommend reading some info and make your own choice. Personally I used to use mobil 1 now I use redline which I feel is better based on oil reports ive read but to each their own.

I use Redline too. Expensive, but can't go wrong with it.
