Yeah, I see what you mean... but no.
The three engines in a year (it was actually 358 days, but who is counting...?) was all on Jasper. Engines 1 & 2 were approved warranty claims, and the engines were replaced. I'm on engine #3 right now.
Because of my unfortunate experiences, I'm going to continue to use an easily recognizable name brand oil... in the proper viscosity, of course... along with OEM filters with the Jasper engine, while it is still under warranty. Not sayin', just sayin'.
However, I have been running the $10.99 Harvest King full synthetic, in 5w-20 flavor, in the 2011 Fusion SE... and the $7.99 5w-30 semi-synthetic in the old Sierra... without any worries.
The Fusion is driven right at 25,000 miles a year, and I'm changing the oil in it every 5,000 miles (or 10 weeks).
