So I'm getting close to the Rinse cycle on our '96 Isuzu Trooper. I have Chevron Supreme 10w30 & Auto RX in the sump now. Should I continue with the Chevron, or switch to Castrol GTX or Pennzoil YB for the rinse phase? What oil brand does the best cleaning?
I'm using 5 quarts of Walmart SuperTech 5W-30 for the cleaning phase in my 2002 4.0L Ford Explorer and at the same time picked up another 5 quarts of the same for the rinse phase. They were selling it for $10 for the 5 quart jug which comes out to $2/quart - a price that is hard to beat. The web pages here list a cheapie dino oil like Supertech as perfect for the application. Why spend money you don't have to for less performance in the application?
