So I'm doing a little maintnance on the truck and I walked in the garage to grab a socket and I stumbled across the 8 spark plugs I took off the truck, I decided to look at them to see if there's any deposits I should be concerned about and I noticed for the first time that the truck was running on 3 different brand of plugs, 2 Champion 3autolite and 3 motorcraft.
The motorcraft were originals and severely worn but the other 5 were just hand tight in the block so who ever did a tune up prior to me was a lazy bastard cause he left cylinders 3,4,8 with original plugs as they were the hardest to get to.
Anyways I'm gonna flush the motor now using desiel fuel gonna do 6qt desiel 1qt oil, run it for 3 minutes then drain, then put in 6qt chepo oil & filter then run it for 15mins then drain. After that I'll run 7.2 quarts of Mobil 1 5-20 with K&N filter and call it a day.
I'll report back on what happens after the flush (good or bad)
