2005 Toyota Tacoma, 2.7L 2TR-FE
The latest Havoline DS sample is on the left, the earlier sample was Pennzoil YB (SM) on the right. I will say that the Havoline sample had a much tougher life. My commute is now 16mi/day stop and go versus the 50mi/day at low highway speeds I drove on the last sample. Also, I had about .8qt less oil in the crankcase as well (long story... but the capacity in the manual is not very accurate and it really takes about a quart less than specified).
I am happy with the results. The oil sheared back, but since the starting viscosity of DS is lower than YB, it appears to have sheared slightly less. It still ended it's life as a 20 weight, but other samples posted from this engine have had similar shearing as well. Havoline TBN held up equally well.
