Valvoline 10W 30 oil in my car. No complaints...

Mobil 1 Full synthetic 5w20. I also use a Purolator PureOne oil filter. They get better oil pressure than Fram. I've also used Valvoline SynPower 5w-30 and Castrol Syntec 5w-20.

Ford Motorcraft 5W-30. Am I the only one not running synthetic???

Don't feel bad emann, I can't afford 40 dollar oil changes either, I have been going to a place that uses semi synthetic for about the same price (25) as normal oil so I don't think that's too bad. Can't remember the brand though.

Oil is the lifeblood of your car. If you want the engine to last longer, then you should use synthetic. I'd much rather spend 40 dollars on oil then a couple grand on an engine. Plus I get a 20% discount!

I use Pennzoil's synthetic oil. Whatever its called. 5w20. Probably need a little thicker living in florida where today its freaking 70, in January, but I'll stick with what the factory says to use.
