Hello,
I'd like to get some recommendations for a good oil to extend the life of our 5.3 vortec. It has 200,000 miles and just occasionally makes a very noticable tap/knock/clicking noise on cold start. The noise goes away after a few seconds or a minute.
I am wondering if it is a lifter, hopefully not a bearing.
In any case, I'd like to try an oil that might help clean out any slight blockages in any oil supply passages. I'm a bit nervous about a "cleaning" solvent and am more inclined to try something more gradual.
The vehicle has been running conventional 5W30 for the last 60k miles with changes every 4 or 5k miles.
I was wondering about switching over to Mobile 1 High mileage? Maybe with a Napa Gold filter.
Comments appreciated.
Doug
