GWOODS:
To add to your discoveries, i have found that the G-35 Coupe seems to behave differently with different types of oil. It really doesn't matter whther you are using dyno, blend or synthetic--though I find blend to be okay nonetheless. I discovered that the G uses more gas with dyno than with blend, and then with synthetic.
I also notiiced that the first 500 miles after an oil change is the worst for gas mileage. The car literally drinks the gas at that point. So, I try very hard to drive 500 miles on the new oil it so that it can stop consuming gas.
for soem reason, the G takes a while to get used to whatever oil you put into it. I also found that the G is sensitive to the brand of oil you use.
For example, when i use the dealers Pennzoil blend 5w-30, the exhast note on the stock exhaust is somewhat muffled, and I get more torque and less horse power from the engine. When I use Catsrol Synblend 5w-30, I get more horsepower and less torque.
These are just my experiences so far. It is normal for the G to use 0.2 to 0.5 quarts of oil betwen oil changes. especially if you switch oil brands and oil types. The oil weight does not make a difference. However, if you stay consistent with a specific brand and type for a while, it appears the gas mileage and oil burning is somewhat reduced. But most G's don't burn oil, anyway.
