I went to Walmart to pick up oil and they do not carry the Mobil 1 racing 4t any more. They now carry Castrol Power RS Racing 4T 10w-40.
Yup about $9 a quart. I just want the best oil for my engine and will give it the best protection. Here is a data test chart for oil comparisons. http://www.amsoil.com/lit/g2156.pdfTry the Rotella T6 full synthetic, only $20 a gallon. Isn't that Castrol around $9 a quart?
It did well in all areas of the testing, except rust protection. If you are storing the bike, that may be a consideration. How many interior parts are made of iron as opposed to aluminum?
Just cuz it's the most expensive, doesn't mean it's better. 9bux/qt IMO is too much for oil.
I am going to return this oil and pick up some more Mobil 1 there this week.My Walmart did the same thing. I found the Mobil1 at Autozone.
Did you know that Amsoil oil runs 10 degrees hotter then the Mobil 1 oil? I ran Amsoil for years in my other bikes. But I do not want to have $100 plus $$ sitting on the shelf. There does not seem to be a local dealer to just pick up 4 quarts, so I now go with Mobil 1.Can't go wrong with Amsoil.
Don't leave us hanging! Tell us your experience with synthetic oils and what caused you to think that way.I have worked on engines for a very long time now. I would not recommend a synthetic oil ever. They do not do anything for your engine. The synthetics actually reduce performance.
