For my final oil on this “sheet”, I used up the Mobil 1 5W-30 in my stash. Oil ran from April 28, 2018-July 22, 2018. Premium fuel/octane and a Fram Ultra filter. Cycle includes a 3,600 mile road trip, the final 945 miles towing in 95-100 degree heat and getting 8mpg. I put the truck in cruise control and just let the turbo wail on the mountain passes. Very happy to not have any fuel dilution. Total of 181 hours on the oil, 34hrs @ idle (19%). Even with the hot towing, the OLM was only at 36%.
So this test concludes my Mobil 1-Schaeffer’s experiment. My wear metals were lower with Mobil 1, but the Schaeffer’s didn’t shear down as much. Generally speaking, I don’t see any issues with either oil. Well, other than the premium price that Scheffer’s commands.
For those interested in the other tests, here are my notes (read right to left on the test sheet)
- 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%. Note: UOA for this cycle found fuel dilution but no wear issues.
- 5th: Schaeffer 5W-30 Supreme 9000 (Jan 2018-April 2018) - Average use spring. A few 100m+ road trips, but lots of idling. Standard fuel/octane. MC filter (no issues). 4,598 miles, 198hrs, 71hrs @ idle (36%), OLM at 36%
