Which oil should I use?
Hi Ya'll,
I am getting ready for first oil change in my new baby. Now I know the pervious owner used Valvoline (conventional) but I'm wondering which weight to use. I drive fairly hard but never over-rev and rarely tow the engine is a 5.0L and it has standard trans. Thanks for the help guys,
Cheers,
Evs

Where do you live? Climate makes a difference. I generally stick to 5W-30 or 10W-30 around here, usually the 5W-30 since it rarely gets above 100 outside here, so it's pretty much good all year.

I have used 5W-30 conventional (usually whatever's cheapest-Chevron, Valvoline, Havoline, etc) for 13 years in my truck. Always get about 13-14 mpg. Last oil change I found some 5W-30 full synthetic on Schucks' hot deal rack & tried it. I got 15.5 & 15.63 mpg on the last 2 fill ups. I was amazed. It was Quaker State Winter Synthetic, but I'd imagine it's the fact it's synthetic, not the brand, that made the difference. No leaks & the truck doesn't burn it. For the difference in cost, at $3/gal for gas, it's probably worth it for me to switch permanently.

My 1993 has 127,000 miles on it, so I doubt it. I understand the synthetic is a little thinner (thus the improved mileage), but if your engine is tight, I'd imagine it'll be OK. Worth a try, you can always switch back if it doesn't work well.
