The oil weight has nothing to do with rough running, just change it every 3,000 miles. Try tuning it up.

I probably shouldn't have mentioned rough running. It is very slight. I am a stickler about changing the oil, which is probably why the truck is doing so well at 26.5 years. I would still like to hear about other people's experiences with oil weight. As far as a tune-up, I plan to it when it is due. Maybe a little sooner.

If the engine is not using oil I would stick with what you are using. If it is you could try 10W-40.

I have a '92 Silverado with 309,000 miles I bought new in 1992. Have lived in NC, TN, KY and have always used Castol GTX 10W-40 conventional oil and changed every 3000 miles. Truck still going strong.
