First off, Outstanding forum you guys have here! I am proud to be a member. I am looking for the best oil and filter combination for my truck. Its a 97 Chevy Tahoe,5.7 Liter with 140,000 miles. I put approximately 6,000 miles a year on it.I only use it on weekends for short trips and sees the highway occasionally. I don't tow with it at all. It does not leak oil and of course it has the dreaded lifter tick at first cold startup. currently I have the oil changed at my friends shop and I do know they use a "Blend" oil. I cannot recall the name. What do you recommend for an oil and filter combo?
