Here’s my latest UOA. This is my oil cycle that included the torn MC FL-500 filter (pics posted in the filer section). Not sure if I’m starting to see fuel dilution because my motor is breaking in or because I changed the oil with very little warm up. Normally I go for a drive to warm everything up and make the oil flow better out my fumoto valve. This time around I was too busy (lazy) and just warmed the engine in the driveway for 5 minutes before putting it up on ramps. The oil was very thick and flowed slowly (it was about 38d outside). I mentioned that in my notes to Blackstone, hence their comments. I’m going back to getting the engine nice and warm before my next oil change.
Other than staying in the viscosity spec better than the Mobil 1, the Schaeffers isn’t doing anything special to justify it’s higher cost. I figured that would be the case, but it’s fun to experiment. I’m already looking forward to dropping in some “cheap” Castrol Magnatec at the next oil change.
For reference, here’s how the four UOAs align (from right to left)
- 1st: Mobil 1 5W-30 (Sept-Dec 2016) - Average fall winter driving with some idling. Did have multiple weekend road trips (200+ miles). Regular fuel/octane and MC filter (no issues). 161 hrs, 32 @ idle (20% OLM at 43%
- 2nd: Mobil 1 5W-30 (Jan-April 2017) - Lots of idling and a few weekend road trips (200+ miles). Premium fuel/octane and MC filter (no issues). 203 hrs, 61 @ idle (30%); OLM at 29%
- 3rd: Schaeffer 5W-30 Supreme 9000 (April 2017-Sept 2017). Easy use with limited idling. Multiple road trips, including one 1,100 weekend haul. Premium fuel/octane. Fram Ultra filter (no issues). 178 hrs, 25 @ idle (14%); OLM at 39%
- 4th: Schaeffer 5W-30 Supreme 9000 (Sept 2017-Jan 2018). Another average fall winter driving routine with plenty of idling. One 500+ mile road trip. Regular fuel/octane and a MC filter (torn!). 192 hrs, 57 @ idle (30%); OLM at 37%
