Time for a oil change. Went to my local sources, and no one had Amsoil in stock. So what are, if any, are the concerns of changing brands, after using the same brand since new? I am thinking of changing to Mobil 1, just because you can get it at any auto parts stores. (Message edited by willmrx on April 17, 2020) (Message edited by willmrx on April 17, 2020) | ||

As long as it's a V-twin specific motorcycle oil, (API-JASO) at the right weight, you'll be OK. The 1125 manual has a specific chart to use "the correct weight oil for the LOWEST temp you will ride in" Some people think just throwing in 20w-50 is OK. I'd recommend following the manual. Going to straight 50 made a big difference for the super hot track days in Florida. Todays oils are so good, I would say they are TOO good. But avoid swapping between synthetic and conventional. I'd also avoid cheap e-bay filters. Spending that much on oil it should be obvious, but I see those all the time  | ||

None..! In my searching for good oils, I've switch in the past. The engine doesn't know..."IF" you don't tell it..! Any good (name brand) synthetic will be fine. I like either Valvoline's VR1 or Mobile 1. Used them in ALL ((twins or not !) of my bike (and car) engines since the late 1980's...with...NO oil related problems. Since California took the Valvoline VR1 away from us a couple of years ago, I've gone back to Mobile 1, 20-50 in my RX and XB. The magnetic plugs are pretty clean (better with the VR1!) and the one "oil" check that I had done a couple of years ago showed no abnormal contamination. So, Mobile 1 it is. Mike | ||

Thanks for the info. Mobile 1 is now my brand. Sorry Amsoil. | ||

I’m in the process of .... likely .... making the same change. I’ve been a faithful ..... buying multiple cases at a time ..... of the Amsoil Signature Full synthetic. It’s been fabulous. But alas, the new Porsche came with Mobil 1 as did the new S5. We’re looking at adding C5 which will also have Mobil 1. I’ll stick with the Amsoil filters but they make it a bit of a pita to do business. I hate paying an annual fee to be a “member” and I grow weary of explaining “why” to dealers. The F-250, which I have a large supply for, will likely stay on its Amsoil diet. | ||

Court is correct, Amsoil is a true synthetic diester oil. Its advantage is great lubrication at elevated temperatures, but it is difficult to find even in the states and impossible to find in Europe, however Mobile 1 is a good substitute. It is not as good as Amsoil, it is a semi-synthetic blend and better than dinosaur oil. | ||

My thoughts precisely. As I understand it. . . . . And I’m all ears. . . . FULL Synthetic - all molecules the same size (Amsoil) SEMI Synthetic - molecules are various size and AVERAGE out to a given size. (Mobil 1) I’ve been using Amsoil Signature ...buying several cases at a time. . . In my Subaru, Jeep, Audi and the Ford Super Duty. But. . . The new Porsche came with Mobil 1 and they did the first service so I let them refill with Mobil 1. Looks like we’re adding a C8 and I understand it also comes with Mobil 1. I still prefer, after reading a collection of technical papers, the Amsoil. He current crop of available oil . . . .pretty much all of them. . . Are amazing. | ||

Why is everyone calling Mobil 1 semi when the 20-50 motorcycle oil states full synthetic? |
