Just acquired a '97 Chevy Silverado 1500, 305 V8, 2wd, Auto, 238,000 miles on the original motor. The previous owner always did 3000 miles oil changes at wal-mart with house brand oil. Engine sounds and runs great, no oil burning, no knock. Thinking about going with Rotella T5 10w-30 with Wix oil and air filters. Good Choice?? or should I go with some Rotella T 15w-40? Shout me out some suggestions I want this engine to last me 300,000 miles. If possible. btw the truck will be occasionally used like 3 times a week to throw trash and cruise down dirt roads or if I feel like it take it to work.
