I wanted to see if I could run a quality full syn oil to 7,500 miles with this particular engine.
I used Oil Analyzers because I believe their testing method for flashpoint and fuel dilution is more accurate than Blackstone’s.
Of the miles on this oil, 2,200 were “pure highway”via two separate interstate trips. The remaining 4,000 miles were “loop driving,” i.e., on the I-275 loop or stop and go driving.
Super Tech was used because that’s what my brother put in it shortly before I acquired this ride.
Initially, my bigger concern was (is) intake valve deposits owing to the GDI. My plan was to use Valvoline Modern Engine for 7.5 k OCIs. M-1 is in it only because I got it on sale.
The engine runs great and the UOA backs that up, other than more fuel dilution than I’d like.
Right now I’m thinking of keeping the OCI to 6k. What oil I use next is still not certain. Probably VME or just stick with Supertech or Costco.
Personally, I think the TBN of 3.1 is pretty good considering the fuel dilution.
And yes, the engine had been run at normal operating temperature for several miles before the sample was taken.
