Oil Analysis 2014 RT -- Amsoil
Attached is the oil analysis report for my 2014 RT SM6 1330. Oil went 4500 miles; 8,400 miles on the bike. Amsoil 10/40 motorcycle oil. I am pleased that the viscosity is 13.18 cSt @ 100C, well within the range for a 40-weight which is 12.6 – 16.3. The TBN is also a healthy 8.7.
Blackstone has a lab tech review each analysis and offer comments which you can read on the attachment. I will offer my understanding of some of Blackstone’s reference numbers. Their “should be” column shows values Blackstone expects to see in a high-quality synthetic oil that has been in service. My guess is they don’t want people to panic if they see a value somewhat outside the original spec for brand-new oil. Some deterioration should be expected. If your sample is out of line compared to the “should be” range, then it may be cause for concern or at least something to think about. Their expected viscosity range is 11.6 – 14.8 – a little lower than what I quoted above for the 40-weight spec. In my case, it’s academic as the oil is well within their expected range and also within the range for brand new 40-weight oil. The “universal averages” column shows average residual element values for engines of this type. It’s “universal” in that it includes all oil brands and types. I inquired for more detail on that and Blackstone told me they have 20 Rotax 1330 samples in their database so far (not including samples from break-in oil samples which they keep separate). Not a lot of samples compared to a 5.7L Chevy or 5.0L Ford! Lastly, their recommendation that I could go 6500 miles the next time is not based on thinking the oil will be in poor condition at that mileage. Their policy is conservative. As long as the current sample looks good, their recommendation is to go up in 2,000-mile increments. If the 6500-mile sample looked good the next time, then they’d say it would be OK to go 8500 miles. This is just their way of doing things – they have no issue with BRP’s 9300-mile interval. They defer to the mfr to know what is best for their engines.
I will leave any further comments or comparison to other oils reported on the forum to the many sages much wiser than I. :joke:
