What engine oil are you using?

I actually found the recommended oil for the TR. Holy crap. Castrol 10W-50

Walmart Canada has it, not sure in the states though. Not cheap at $16 bucks a bottle.

Ive got in arguments with bike shops and auto parts stores that 10W-50 actually exists. Most places just tell me it dosent exist and it must be a typo in the manual.

I hate dealing with the guys across the counter. If its not on their computer screen, than it must not exist and your dumb.

I f%*Ked up last night doing my oil change. Manual says 2L exactly will top it up. So I bought 2 bottles not realizing that a bottle is just a tad over 900ml (brain fart). Enough oil to just touch the tip of the dip stick. So looks like ill be packing my ass aboard the Mitsubushi and going to Walmart.

So is pajama pants, crocks and a AC/DC jean jacket considered over dressed for Walmart?

Overdressed, probably. Swap the jean jacket for a wife-beater and you'll fit right in.

Depends on the wal mart

Castrol 06412 Power RS Racing 10W-50 4-Stroke Motorcycle Oil is what I use. If you contact Castrol they will tell you that it is a completely different blend of oil and they wouldn't recommend using one for the other. But if you compare the descriptions of the oils on castrols website, they compare word for word. Castrol says some KTM shops in the U.S. carry the oil. The KTM/BMW/Yamaha/Victory shop near house does not.

I call B.S. on Castrol.

There's no way I can remember back to March, haha.

But, I wanted to share with you that I did some recent research into the BMW GS650 engine since I was curious about which oil to have my customers use. BMW originally specified BMW brand 15W50 oil be used in this engine. Anyone familiar with BMW brand oil knows that for the last 15 years, this oil is actually re-branded Golden Spectro and should probably never be used. After speaking with several BMW mechanics, I am told that they switched their race bikes all over to a grade 40 oil, more specifically, M1 4t 10W40 gaining excellent results in shifting, power, and even idling. I see no reason why M1 0W40 or Rotella T6 5W40 couldn’t be used in the GS650 engine unless you do not plan on changing your oil prior to 1500 miles.

I use Torco T-4R. It was recommended by the guys at Bills. And it comes in 1 Liter bottles. Makes a 2 Liter oil change pretty simple.

I would have taken it for a ride to get the oil to operating temp. I reckon it would have been spot on when you rechecked it...

I use Mobil 1 4T 15w-50 part # 98X514 which is in a 4 litre container.

I used motorex 10w60, but a bit expensive..
summertime here in alicante spain is very hot, 35-39 degrees, and to do gravel, below 25km/h do not cool enaught..

Found this at pep-boys.

I use Amsoil Formula 4-Stroke 0W40 in my 310.

I know this is a TR650 forum area and I was just reading for research. In the 250 x-lites I'm running Lucas full synthetic 10w40. Both bikes are still on original motor, no rebuilds with lots of hours. So...But I am always interested in improving things.

I was looking for on-line comparisons and here's one from 2006, all I can say is there is a science to this; are there any more current comparisions out there? And if I follow along with the Lucas products in this comparison...I may be looking to switch.

And, if the current Amsoil products are still up to performance level of 2006; winner. But then again they performed (or paid) for the test.
Read into it what you want and form you opinion; later...

Found a 2nd edition test of the above from 2009, kind of the same results.

The Castrol is what I currently use in my 310. 5 bottles left of my case and will likely follow suit to Mobil 1 0W-40. But... Quart bottles of the stuff are sold out at Wal-Mart because of Tinken ;-) (gals. available though for cheap)

I wouldn't use the Mobil 1 designed for cars. It is not formulated to go through transmission gears or wet clutches. And the specs surely won't be right for our TR650's. That would be an instant warranty denial.

This is exactly what motorcycle specific oil manufactures want you to think. This way they can sell you their specific oil at a premium price. The truth is that not only do some of the auto specific oils work perfectly with motorcycle engines and wet clutches, in many cases, they actually out perform motorcycle specific oils.
