Zipp, why pay for semi syn, when you can get full syntheic.
full sythetic is a much better oil and can take abuse much better than a synthetic blend. Most people buy semi-syn. because it's cheaper. I've been using full synthetic since the seventies and have nothing but good tom say about it(All snthetics)......Angelis
