can't find my manual - what type of oil to use?

Can someone let me know what weight/viscosity of oil i should be using? Thanks!

For the summer months, I use full synthetic 10w-30.

You will get a million anwsers. For the summer where I live I run 20W-50.

currently running 10w30, will be running 20w50 next year to hopefully shut my lifters up a bit

If your car is in good running order then 10W30 should be fine.

motor oil.





































I live in a climate like James does, so I also run the thicker stuff. Spec is 10W-30 in summer temps.

10w-30 is the oil the haynes manual says to use in hot weather. But I doubt you are going to damage an engine using any major brand of oil regardless of weight. Out of all of my time browsing car forums I have never seen a case where an engine was destroyed or severly damaged because the wrong oil brand/weight was used. I am sure 10W-30 would be perfectly safe in my engine, but when it is 98*with 80% humidity outside and I am idling in the Mcdonalds drive through buying my fat ass lunch with the A/C going I feel safer with a bit heavier oil in the engine .
