Engine oil grade help

3 posts in this topic

So I noticed the recommended oil was 10W-30, but the local mechanic gave us the SAE 40, which I noticed only after he left. Would that make much of a difference? Should I change it out to SAE 30, still?

Straight weight 30 or 40 is much different than 10w30. I suggest reading up on it a bit.

Are you sure you're not supposed to be 5w30? I have a 1996 626 and it's 5w30 all the way.

Woops, my bad. Yea I meant "change it out to 10W-30". Thanks for that! I was busy these past months so I wasn't able to update here anymore. We had it swapped out to 5W-30 as recommended by a friend. Honestly didn't notice any difference when we ran it with the SAE 40 for a bit, but we thought it would be better safe than sorry later on. Thanks!
