This was a "rinse cycle" so to speak, on my pickup truck that I purchased the first of March. When I purchased it, the truck appeared to have been well cared for and drives like new. Truck was purchased with 81582 miles and this oil went in 100 miles later. The truck is driven gently, only hauling an ATV occasionally. There were several cold starts at around 0F (+ or - a few degrees) but that's about it. Cumulatively, it saw about 300 highway miles, with the rest in hilly farm land. There's nothing to see here, but thought I'd add to the 5.0 reports on the web. Wonderful engine. 5.0 V8 MC 5W20 Fram PH10575 Fram air filter (don't know the number, but appeared new at purchase time) Engine miles 87,289 5,607 miles on oil No make up oil.
