Wondering if I can use 5w/30 instead of the 5w/20 recommended in the owner's manual. I've only found one place that sells one brand of the /20 conventional, but I would like to use synthetic. I can't remember what the second number in the oil rating meant.

Thanks

 

Of course you can use it. Using 30 may cost you some gas mileage and the car may not idle as smooth/quietly with 30 from what I've experienced that is. But it can't possibly harm the engine at all - the oil in fact would just have better protecting properties in it than 20.

The 2nd # means viscosity.

 

I use mobil1 5w-30. No problems here. A lot of people use 5w-30 for their EP3's.

 

I used Redline 5w20 for my first oil change. That stuff doubles as weight reduction on your wallet too...

I haven't found any other synthetic in 5w20. Running 5w30 won't hurt, it should be the most cost effective and definately the most convenient to find.

 

I've been using Mobil 5w/30 in my ep since the first oil change. No problems at all.

 

i used it, eliminated that injector sound, however the car felt a tad slow, went back to w20, injector sound is still gone and i have my wee bit of speed back.

A lighter oil makes the RPMs go up faster - from what I've read here.

 

5w20 is hard to find... Just look in most gas stations all that is there is like 10w30 it sucks but no 5w30 should not hurt your engine...

 

sure can...
