hey guys, has anyone mixed synthetic oil with lucas? i kno they say not to mix synthetic with anything, but then again "THEY" say not to do alot of stuff in life,lol.

im currently running 10w30 synthetic and want to start mixing them because, i've heard from a couple of buddies of mine, and online that its supposed to slow down oil consumption ( because im around 1qt every 1k miles) and also because my valves are noticeably loud (yes, they were previously adjusted by professionals..) and i also heard it quiets them down a bit... and all the other magical stuff its said to do on the bottle...

so, yes, do it? because....
no, dont do it! because....
or do it with non synthetic...
