NGK spark plugs are excellent and have a well earned reputation for quality. They also wont break the bank. AMSOIL Signature Series 0W-30 synthetic motor oil is a phenomenal product; improved fuel economy, increased wear protection, easy winter cold engine starts, lower emissions, reduced maintenance costs.Hey im getting ready to do an oil change and tune up this weekend, so i was trying to get some advice on what engine oil and spark plugs perform the best in a 1991 350 tbi chevy caprice. Not worried about the price at all.
Buyer beware; semi-synthetic oils can have as little as 1% synthetic oil present in the blend and still be legally called a semi-synthetic oil, but with a much higher price than petroleum oils. If the oil bottle doesn't tell you the percentage of the blend, buyer beware.I've always had good luck with Autolite's, I like WIX filter's, I'm not overly picky about oil, no no-name stuff but brand name and lately using the semi-syn stuff. I go 3-5k between changes and can see thru the oil all the time.
