EQUIPMENT MAKE / MODEL: Honda Insight, 1.0L 3-cyl
OIL USE INTERVAL: 5,160 Miles
TOTAL MILES: 31,513
OIL TYPE & GRADE: 2.9 qts Mixture of Havoline 5W-20, SM, GF4 (85 oz.) + VSPOT (7.5 oz.)
MAKE-UP OIL ADDED: 0 qts
FILTER: Honda Civic OEM (Oversize) Filtec
ERIC: You can see the differences in this oil (mixed with VSpot) and the last oil you were using in the slightly different additive packages. We think either one is going to work well for your Honda, which seems determined to make the same wear regardless of miles on the oil or oil brand. That's great, and we see no reason not to run more miles on the next oil change. The trace of moisture is from condensation and not something to worry about. The TBN read 3.6, still active additive remaining (a reading of 1.0 or lower is too low). Looking good! Go back to 6K miles next time.
My Comments:
My hope in mixing the VSPOT (Valvoline Synpower Oil Treatment) was to raise the viscosity to 30 wt in an attempt to reduce aluminum wear. I was also trying to boost the already high moly level of the Havoline 5w-20 oil to match the Honda GF3 oil in hopes that this might be helpful in keeping the iron wear as low as possible.
It appears that the aluminum wear was not reduced by the slight viscosity increase for this run.
I believe this engine has an aluminum block with sleeveless cylinders and roller cam followers which may account for the higher aluminum and low iron wear. This engine also has substantial piston slap noise during warm up.
My current run is Chevron 5w-30, SM for 6K to see if less moly has much effect on iron wear. I may then try GC 0w-30 or M1 0w-40 for 7.5K.
Suggestions and comments welcome.
