sam2.0 10 Posted May 21, 2013 I've changed the head gasket on my car, and would like to do a oil & coolant change. Is it best to do a "flush" cycle with some cheapo oil and coolant before using the recommended products? Or, as they are both cheap enough, just do a change with the correct product and do an other in 3-4k? Also, what oil for a 2.0 16v (140k miles) I've read the best is Quantum 10w40 Semi, paired with G12++. Quote Share this post Link to post Share on other sites
