Is it ok to mix full synethic with synethic blend,I'm changing oil in a day or two. reason is i bought a 5 qt. jug and still needed 2 qt's and they didnt have it in the quarts of the brand i bought. i went to afew stores and couldn't find any..i figured it proly wouldn't matter but i figure i'll ask the experts...

thanks guys in advance

shawn..

 

It's fine as long as the viscosity is within proper range.

 

Ok,wasn't to sure.. thanks..
