Ok my Evo came with 10w-30 but my friends came with 5w-30. What should I use??
Thanks

 

I'm running 10-30 but planning to switch to 5-30 when temps start to drop below 30 deg.

 

Neither should cause ill-effect unless you're running your car very, very hard in harsh conditions. There's a graph in the manual that states what temp ranges certain oil wieghts are good for. I think 10w30 is rated down to -30F by mitsubishi. You'll want to look it up yourself though.

EDIT: FWIW, I run 10w30 in the summer and 5w30 in the winter.

Have u consider Amsoil?

 

0w30. That stuff rocks!

 

Sounds good.

Thanks

 

10w-30 year round... cali...

 

Is it okay to mix oil?

I have the Mobil 10W-30 in my car, but the oil level is at low. I can't find the 10W-30 at all, only Mobil 1 15W-50 or Mobil 1 10W-40...

So I was wondering if I can run like that... until I get the good oil in a months or two...

 

I think you're supposed to use 5w30 if you get alot of below freezing tempature like us in MN. It helps warm up your car faster. If you're in a warmer area where you do not see alot of freezing temp you should just use 10w30.

try advance auto i know that they...well we...(I work there)

 

Yes, if they are both fully synthetics. You will sleep easier if you mix the same brand. I wouldn't go ape and mix between large grade difference though.

 

Always Mobil1 5w30 for me.

 

Mine came with 5W-30. I use it all year. You can use 10W but switch to 5W for the winter. It will help the engine on those cold starts.

 

I was running Mobil1 15/50 in my Eclipse 2.4L. I live in pretty hot area of So Cal.
