I'm looking for oil recommendations for a 99 Silverado 4.8 with 215,000 on it. The truck is old, and shows its age but so far has been 100% mechanically. I've had the truck for about 5 years and 50k now, and have been doing oil changes every 3k, plus previous owner had oil changes done every 3k at the dealership from the date of purchase. I would love to see this truck get to the 300k mark, and I figure now is the time to get serious about what I'm running in it.
-Currently using Mobil 1 5w-30 high mileage and purolator pure one filters.
-No known issues with the drivetrain
-Using a little over 3/4 quart oil every 3k
-Live in East Tennessee, temperature extremes are 10F-100F normally. Garage kept when at home.
-I'm a very easy driver, I baby both pedals. Average commute is 8 miles one way, with only 2 traffic lights, a stop sign and a roundabout. 2 lane highway. Everything else is 50/50 city and highway with the occasional steep mountain road.
-I have not tried any other oils. Walmart or Amazon are my preferred places to buy.
Should I keep doing what I'm doing since it works, or is there a better option? Should I do a UOA of the Mobil before I look into changing?
