Yea, it's tuff remembering last week, let alone near 20 years ago. All I know is it got taken care of under the extended warranty, which I was super thankful for, as my dlr billed Honda a substantial amount iirc.I can't imagine it needed an engine rebuild. Hone the cylinder, add new rings, should be good to go. Otherwise under warranty they replace engines. I've never seen oversized pistons or cut cranks on a warranty job.
Exactly the same oil i use and same story. 17+ not a drop lost.My '17 SP changed to Amsoil full synthetic at the end of the 500 miles break-in period and now have almost 7000 miles on it and it hasn't used any oil. The quality of the oil is probably the reason for the pristine dip stick.
In decades of owning cars/motorcycles and following the owners manual, I'll worry if I ever have an oil related engine failure.The Manual might call for conventional oil but I still prefer a 100% ester-base stock synthetic oil like Amsoil or Redline, etc. Last I heard Mobile 1 is not full synthetic but uses enough percentage of synthetic that the government say they can call it synthetic. (Freaking Politicians ) I like to see the base number close to the top weight number, like 10w-30 rather than 10w-40 or 50 as it has less viscosity improver additive and more real oil. And if you run a synthetic you don't have to worry about viscosity thinning at higher temps.
Oil type is one of those hot-button subjects, like gun control, everybody has an opinion but talk to some of the real oil scientist as to what goes into an oil for specific uses and it will make your head spin.
The manual doesn't call for conventional, it just calls for Honda oil's. Honda makes all 3 types.The Manual might call for conventional oil but I still prefer a 100% ester-base stock synthetic oil like Amsoil or Redline, etc. Last I heard Mobile 1 is not full synthetic but uses enough percentage of synthetic that the government say they can call it synthetic.
ProHonda GN4 is conventional oil. I've attached page 224 from the 2017 owner's manual.The manual doesn't call for conventional
BMW has always done things "different" with oil. The BMW factory calls for the ZF transmission to use the BMW synthetic tranny oil but when you drain it you see massive wear from the brass synchros. Switching to Redline MTL shows very little wear with smoother shifting. Understandably I am upset with BMW and their recommendations, it is VERY expensive to replace the synchros in the ZF transmission. So how did we get started on cars..., well my brother owned the K100 BMW liter bike and always had issues with it which I won't enumerate, so don't get me started on BMW.Now a days cars use 10-60 from the factory in things like BMW M cars, so wth?
