I recently switched my 92' Z to Mobil 1 high mileage formula, not because of high mileage (it has 41,000 miles) but I've always used M1 10w30 since new, M1 HM has plenty of zinc and also seal conditioners which I feel is important to our aging engines. I also used the Bosch oil filter. I get my M1 at Wally world so for a complete change oil is less than $50.00
