Hello,
I put Pennzoil 10w30 instead of 5w30 in my USA 2000 Focus ZX3 as the oil-change place ran out of 5w30 I didn't have the time to go elsewhere, looking for 5w30. Do you think it's a problem?
We're getting warm weather in California and theoretically should be ok, but still, I think the car starts a bit harder now. I don't hear valve rattle or anything, so that's a good sign.
Regards, Stan
