2016 Honda HR-V, 6205 miles, Red Line CVT (drain and fill x2)

[michael007]

Total# of miles on this UOA: 6205

Total # of miles on the replacement CVT: 29406

Surprised to see the acidity number is even worse than the last UOA in December '23. Only thing I can think of is the CVT doesn't like the larger sized tires that were installed (225/65/17 from 215/55/17).

VOA, thanks to @Revving2Redline :

Looks just fine... What made the original trans die at 200k?

Dealer said the belt was in pieces when they checked the magnet.

All I did was back it out of the driveway, it got stuck in some semi deep snow and died. No noise of any kind that would indicate a problem and no lights on the dash. The engine would just rev if put into gear.

Honda took care of it free of charge under a warranty extension:

That's awesome that they covered it since it was a known issue. Thanks for sharing that.

In your opinion, would it have continued to be fine or are 6k OCI's appropriate?

Virgin TAN for Honda's HCF-2 is 0.25-0.4 depending on the formulation date

For Red Line, I could only find the TBN which is 3.

I've read comments on the forum saying the oil should be changed when TAN is x4 compared to virgin oil.

I've also read it's good to change it when TAN coincides with TBN so when it's already at 2.46 after only 6k miles... it doesn't seem like it's going to take much more to get it to 3.

This never seemed to be a problem until I installed lifted springs and now the larger sized tires

UOA's from the previous CVT:

You'll see TAN was highest right before the failure... The car was stock back then.

Unfortunately, I'm not informed enough to measure "Condemnation" points on transmission or gear oil. The oil lab would be the best source for that. The only information I have on that is engine oil.
