Hiya all,

Every now and then, if I let my van sit for a while, she fires up and clacks
something awful. I've fixed this before by dumping half the oil and topping
off with Marvel and running until the noise subsided. Then I drained all the
oil and refilled, replacing the filter at the same time.

My question is this. Is it a bad idea to mix Marvel and Redline? Say half a
quart. I run Redline 10w30 in the winter and 20x50 in the summer. I've just
never mixed synthetic oil with Marvel before and I'm wary.

Thanks,
