I have 2 qts of 5w30 Peak conventional and 2 qts of O'Reilly 5w20 full synthetic. I was wondering if it would be ok for them to be mixed together. Is there any additive clash that I need to be worried about or would you just say mix and go? The OCI will be 3750 at about 50/50 city/highway use. thanks!

YOUR ENGINE WILL BLOW UP. Now that we have that out of the way.. You will be fine, any API certified oil should mix without issue. (Sorry I couldn't resist on the first part)
