I just found out the shop I got my oil change from, replaced my 93 integra oil with 15W 30 oil. Is it okay to run this? I live in CA....

 

I used Mobile 1 High performance motor oil which i think was 15w30, or could have been thicker, with a Fram double guard oil filter and when i changed the oil the filter seem to be clogged with oil..so either the oil was too thick or the filter was crap....but im not gonna chance using a real thick oil again.

 

you should be fine but i would take it back and have them put 5w 30 back in it ... i personally dont like thick oils ... i try to stick with what the factory recomends
