I know the bike calls for 20-40 oil and it says use Indian motor oil, but what other brand could I use. I really dont feel like driving 2 hours and get oil from Indian dealer. Thanks
I tend to go by the specs of API SM and ILSAC GF-4.I like Amsoil and have it in all my current vehicles, but not sure if I will be putting it in my 2015 Cheiftain when it arrives. Amsoil currently says that they do not have a recommended oil for our Chieftain. If you do use amsoil then I would probably recommend the 10-40 vs the 20-50 based on what I read on other forums.
Can I ask why you are not a fan? I have used it exclusively for years in my HD, Goldwing, and soon my Indian and am just wondering why?I'm not a fan of Amsoil. I just gave away a case of 20W-50 amsoil for free. I will use any other 20W-50 available when I purchase an Indian.
I agree. Buy enough oil for a few changes and use the manufacturer's oil. Using the wrong weight or grade is a bad idea. If you want to pick different oil, use Wesson. You might get a date with Florence Henderson.I've been working in the petroleum industry for over 35 years and motor oil discussions are always near and dear to everybody's pocket. Over the years, this is some of what I have learned regarding motor oil. 1st, car oils are not the same as motorcycle oils, (especially air cooled engines), like Indian, Harley and the like. When a manufacturer says to use a certain grade ie; 20w50, 20w40 and so on, you must remember, these companies have a room of engineers which disect their engines to the micron. There's bearing wear, ring wear and all different types of metal, chromium, magnesium, brass and so on. There's metal fatigue which goes on in an engine. Heat is the biggest culprit to this wear. Then there's Synthetics, full synthetic and para synthetics. Both have great qualities reducing heat which causes wear. One big issue is additive packages. If your engine, tranny and clutch oils all use the same fluid, Don't use any oil, with the Moly additive. This additive is does not work well with clutches. In time they will start to slip. In closing, when you see a dealer carrying the manufacturers oil for that bike, USE IT!. Like I said, that room of engineers they have, know exactly what additives they want in their oil to give that engine so it runs the most optimum and gives it the best protection it needs. When you spend 20,000 + for a bike why not use the best oil for it. Don't ever think that a 20W40 in a walmart is the same as a manufacturers labeled oil, it's not...
