hmmm... kinda the same as doing a search, 5 different answers and 3 of them i have read bad things about elsewhere.:dontknow:
i have read all the info i can find but the more i read the more i'm not sure, especially for the sm5, what engine oil do you run in the 998 sm5[manual clutch], that won't damage the clutch and preferably not foam like brp, and preferably i can buy at advance or oreileys.
There are a number of lubricants that will work in the 998. Especially if you are changing at the recommended 4,500 mile intervals. That is where most oils, including the BRP lubricants, begin to suffer a great deal of viscosity loss due to shearing. If you plan to go farther than 4,500 miles on an oil change. Or if you want better protection. There are only a few lubricants that will do the job.
Of course, there are a number of oils which work in just about every other wet clutch application that will not do will in the 998. And this is probably what is causing you understandable concern. You certainly do not want to slip your clutch. It can be a very expensive error.
The BRP lubricants do tend to foam more than most. Of all the oils I have tried, Amsoil foams the least. Virtually not any foam at all. With the BRP oil and others, you just need to wait until the foam dissipates before you can get an accurate reading.
There are more oil and tire threads than any other subjects on the forum. There's an incredible amount of info available here from folks that put a lot of time and effort into posting the data. It's all here. What's you'll get starting a new thread is a couple hundred more opinions. Do you just want someone to TELL you which oil to use?
LOL....Ron sells amsoil.SO Thats what hes gona tell you! Its great oil for sure.BUT For the money the castrol is the best choice.
