Today I had to get some things for my wifes car and some oil for mine. I had my wifes car on the brain and without thinking, I grabbed 5w-20 which is what her car runs. I didn't realize that's what I had until I had half of it in. I have an 08 ss/tc and I want to know if this will hurt the engine... I really don't want to spend $40 on another jug of oil.

 

$40 for a jug? Is that 5 quarts?

 

5.1 quarts. That's not including $14 for a filter.

 

return it, buy 5-30. better safe then sorry.

 

Already in. Didn't realize it till I had half the jug empty.

 

$40 is alot for oil. I paid $27 for 5 quarts of 5w-20 Mobil one synthetic at Walmart. And then $7 for a filter at orileys

 

I guess I've been getting screwed then haha. Owell I know its expensive but I've come to deal with it.

 

Ya try Walmart. Cheaper there.

 

Just drain the oil you put in your car slowly and throw it back in the jug so you could use it for your wife's car and buy mobil 1 5w30 for your balt! Would'nt run my balt with 5w20...

 

I don't think anything catastrophic will happen, lulz. If you can, just drain the oil and use it in the wife's car.
Go to Wal-Mart and grab 5 quarts of 5w-30. Don't forget the oil filter as well.

 

Whether its catastrophic or minor I don't want anything to happen. Might as well be safe and get some more unless someone can chime that knows first hand it won't hurt anything. And it won't go in the wifes car cause hers takes syn blend and has since bought new in 07.

 

Nothing will happen. You might burn some oil up but that's about it

 

run it. You'll be fine.

 

You'll be fine. I've been running 0w40 in my car for 100,000 miles. Still not burning any.

 

What's wrong with running 5-20. That's what's in my car

 

I'll probably just run it for this week. My father in law is an owner-operator and gets oil for pretty good prices. Ill see if he can get me a deal on some.

 

You may not have any problem with your car but you have to check cause if GM recommend 5w30 and your using a different grade of oil (5w20, 0w20, 15w40 lol....) it may void the powertrain warranty. But im talking about ss/sc and ss/tc i don't know maybe ss 2.4 need to be run with 5w20

 

My warranty is longggg gone and I've been using that oil since I bought the car.

 

Don't listen to her! Walmart makes cheap recycled oil lol
Hence the recycling symbol

 

No they don't.

Good try though

 

You can buy Mobil 1, Valvoline, Royal Purple, etc etc etc

Now on the TDI forums they have data supporting why the walmart oil isn't any good. not they use recycled oil so it must be bad.

 

yeah its not walmart brand, its Mobil just sold at walmart. Compete change for around 30 bucks

 

Havent i heard in the past to use a thicker or thinner oil in the winter? No idea why....

 

I think thinner for cold winter starts.

 

Oils have multi viscosity ratings. The 5w is the rating when the oil is cold and the second number is the rating when the oil is at 100 degrees. The lower the number the thinner the oil. The oil the op bought would have the same viscosity in the cold as a 5w30 but the oil will be thinner at operating temperatures since its a 20 and not a 30.
