Bad fuel or oil change?? 6.0 running bad.
I changed oil yesterday. Did nothing out of the ordinary. New oil, same T6 as before. Same oil filter. Filter snapped into cap just fine. New O ring on cap. Dumped in 14 qts. Fired it up with no leaks. Drove home.
This morning started truck and I noticed it stumbled while idling. I let it warm for a minute, then proceeded to chug up the hill as normal. It ran bad till warm. By the time I got to the interstate (4 mi) it seemed back to normal.
Then I started it again tonight,noticed it stumbling again, wife even said something doesnt sound normal. This time I gave it some throttle going up the hill, enough to where gravel should have been flying with wheels spinning, and it only revved to maybe 1500 rpm.
So, the only thing I can think of oil change-wise is a oil pressure leak around the cap.
Or....(this just dawned on me)..BAD FUEL! Just remembered I filled up with 26 gallons yesterday right after I changed oil. Just checked the slip and diesel fuel was used..*WHEW*..Oregon sucks as far as not being able to pump your own.
My moneys on the bad fuel.
