RE: SURPRISE: Redline oil might not be the best out there
i use to run pennzoil at 32-1 for years.after three years of runnig it in a dle55 i had to replace the crank and rod,lower rod bearings were bad. not the blame of pennzoil just what happens on the budget engines.
what i did notice is the carbon build up on the top of piston,not much but still there. then when they change the name to Outdoor oil and couldn't find Air Cooled, i just switch to Redline at 32-1,and what i found after running it in another dle55 i had no carbon at all on the top of piston.and it doesn't completely burn off, there is a thick film of it on the cylinder wall.
