I cut an oil line last week and took the car to our local garage to have them fix the line. I checked the bill and it says he put 5w-30 in the car. Is this right?! Should I change it? If so to what?

you need to find a new mechanic

+1. I'd say the vast majority of guys on here use 20w50 but it can vary depending on your location and what kind of driving/winter weather you're heading into.

Dougs951

Well it really doesn't get that cold in Southern MD so...

bigdeano

20w50 should work just fine for you.

Dougs951

So change oil tomorrow?

yeah, 20w-50. I don't think it will hurt your car as long as you don't rev the **** out of the motor. You might read lower than normal oil presure.

DanR

funny my enhine builder said to use mobil 1 15 50. Guess this should get some comments!

Just switch it out whenever you get the chance. Its not like its gonna get up to 90 degrees up here anytime soon so that 5-30 should be fine until you get some new juice in it.

I always ran that car on 20w-50 so you shouldnt have any problems.

Thanks, now I just need it to blow warm air...off to bleed the coolant...again.

5W30 is great................. if you live in
Alaska!

20w50 is what I just switched too after running 10w30. Oil pressures are much more stable. In most instances, when shops dont know what oil a car will take, thay use 5w30/10w30. I have customers that request 14w40 or 20w50 because that's what they want. That's what u need to do.

if it's a Porsche shop and they put 5w30 in it. BURN THE BUILDING DOWN.

Dougs951

nope not a Pshop. I think that was my major mistake...

stock porsche recommends 15w40 shell rotella for most climates- i run 20w50 for mine but i track it.

bigdeano

isn't shell rotella a diesel oil? I seem to remember my dad using that in the duramax before he switched to amsoil....
