Where do you get 20W-40 oil???

[Thatguy331]

Been looking around for the 20W-40 oil that the bike manual says to use if you're riding in 60+ degree weather, but that is a very rare type.

Where do you guys get yours, or do you substitute another type, like 20W-50?

Mobil 1 Extended Performance 15W-50

I use these two oils. If you use the search function you will find a huge amount of links explaining why people use different oils.

thanks for that, super sock puppet moderator! I didn't really want to see another oil thread when I looked in here.

After seeing a lot of motorcycle enthusiasts using Rotella Full Synthetic 5W-40 all year long, I went to Wallmart (first time in my life at Wallmart ) to pick up a couple of gallons... did my oil change this past wkd and I am really happy, as I can feel quite a big diff when switching gears.

I used Castrol Synthec before and had not felt such a diff between oil changes.... I think I am going to stick with Rotella 5/40 from now on

Wavex, are you saying that the gear shifts are smoother? Yes, I know---and read some of them---that there are Fzillion threads on oil, but I think I'll try Rotella if the shifts are noticebly smoother. I have never, ever used a synthetic oil before. I'm currently using Yamalube (20-50?). No clutch slippage?? The local Yamaha dealer said that the recommended viscosity is not even available any longer. Yamalube is so expensive (since one must buy it at the dealer) that I could probably switch to Rotella for same or not much more, huh?

have used rotella in my quad and it makes a huge difference in the shifting. I will be putting it in my bike this weekend! Time for the 600 mile service baby!!!

Yeah guys, just try it and report back... I for sure did not expect such a drastic change. I hope it`ll last for a while or else I`ll have to change my oil more often

I have started doing a little more indepth oil research after a guy from Amsoil came in and gave us a hour long sales pitch on how good it was. He had some good points here and there but it got my currosity up.

Turns out that most shelf oils are all Base III stock which isn't really synthetic. Even though they say synthetic, which all started when Castrol claimed there Base III a synthetic. After a huge lawsuit they allowed that and everyone went along with it. Mostly though this is only in the states. The only Castrol that is Base IV is some stuff from Germany.

Pensoil Platnium is as Base III, there is talk that Mobil 1 has gone to a base III and there are some other large names that have droped their "synthetics" to base III oils.

Motul is a combo of base IV and base V and in some cases strickly base V.

Not sure if this base stock has been talked about much. But its worth looking into if not.

Mobil is and has been as far as I know a true PAO synthetic. If the Amsoil guy said different it is just not true unless something has drasticly changed.
Rotella is a synthetic oil made from crude oil. It has the same properties.
Mobil one is basicly the only READILY available true PAO synthetic.
Rotella stnth T is a kick but oil too. I just buy mobil one because I like it.

Here is what happens when you run just plain mobil one in your car for 18,000 miles only topping up what goes with filter changes and loss. It is tested by blackstone oil labs.

And a test that made 14000 miles with blackstone labs testing on Amsoil. Both are excellent oils.

Amsoil is pure PAO synth oil as well, its just not readily available and sells at huge premium.
