I switched over to Full Synthetic oil yesterday when I changed my oil. I got 7 quarts of the Super Tech Full Synthetic from Walmart. Got the Fram Tough Guard filter (I read the regular Fram filters suck). I've been having to use the 07 Trailblazer V6 filter for my Isuzu (same engine (Vortec 4200) cause Walmart doesnt stock the filter reccomended for the Isuzu Ascender... Which makes me wonder why the filters are different for the same engine?
Anyhow, so far the synthetic seems to run smoother. Wondering how long I should wait before changing it.. 5,000? 7,500?
