I've read almost every thread pertaining to the issue of the type of oil to use in a Sea Doo.
Although there are some great posts on this subject I've focused on two posts:
1) SeaDooSnype recommendation to use Quicksilver PWC because his engine is a 787 and there is no Sea Doo shop nearby;
2) Dr. Honda, who stated that Quicksilver Premium Oil (QSPO) is a very good substitute for XPX oil, conditioned that it is used in earlier Sea Doo's, primarily 587 engines.
Having used Valvoline TC-W3 for the past 2-3 years because I did not believe all of the hype about only using a API TC certified oil, the past month found me learning how to remove an engine from the hull and disassembling it to replace a defective crank in my 93 GTX because it froze. (replaceable parts were in good shape, albeit there were signs that the bearings had overheated. The defective part was the crank itself because of a defect when manufactured)
Because I have replaced the crank ($250) and two years ago I had a complete engine rebuilt, thus now, again, I have almost a new engine, to be on the safe side I've decided to follow the Operators Guide and the recommendations on this site and use API TC oils.
That said, as pointed out above, I am focusing on two threads authored by SeaDooSnype and the good Dr. Honda in deciding what oil is best for my 587 engine.
Although Dr. Honda suggests QSPO is a good substitute for XPS oils for a 587 engine, I noted that the 1993 Operators Guide (OG) urges the consumer to use Low Ash API TC oil. QSPO is not Low Ash, but is an Ashless API TC oil.
That said, I found the OG recommendation odd because of the fact that the first generation XPS engine oil that was used for 93 SD's was an Ashless oil and was changed a few years later to an Low Ash because of the higher temperatures generated by the 787 engines, the type owned by SeaDooSnype.
Based upon further research I learned that although Low Ash oils typically provide added protection, however, contrary to what most people believe, whether or not the oil is Low Ash or Ashless should not be the focus point, but rather what is more important is the oil quality classification, i.e., NMMA/TC-W3, API TC, etc.
Based upon the foregoing, since I have a 587 engine, thus there are no rave valves in my engine, using the Quicksilver PWC synthetic blend would not provide and better benefits than using QuickSilvers Ashless API TC Premium (not Premium Plus) and should keep my engine running for another 15 years.
On the other hand, would I be better off using Quicksilvers PWC synthetic blend?
Although SeaDooSnype uses full synthetic QS PWC engine oil, I shall presume, arguendo, that the synthetic blend and full synthetic are closer to one another than QS Premium.
I am not trying to offend anyone, just trying to get the facts as Joe Friday would do. What do ya think?
