4 USA quarts is 3.8 litres, which is 2-300 cc too much but not excessive.
I'm at 245,000 kms, yamalube from day 1, change oil every 10,000 kms, filter at 20,000, no oil consumption between changes. YMMV
GV - you're right on the conversation: however a container of oil = 1 liter

Also thanks for your input on the timeline of your oil changes - nice to know that we can stretch the intervals !

1 quart = 946 ml
My Honda's need 3.4 qt and for years I have always put in 4. I do it on this bike too. No detrimental affects thus far that I can tell.

I put a gallon in mine. After 5-6k miles. It has just dropped to the very top of the sight glass. Dont know how much that is.

That window never works for me. I even wait 1 minute to look at it. No oil... argh!

Results look good overall. As far as the "overfill" being a dry sump it doesn't really matter howuch oil you put in as long as it doesn't overfill the tank. I know the yami is an odd duck design because there isn't exactly a tank but if you've been doing 4 quarts it seems like it works. More oil means better cooling also.

Seems strange to me that so many owners choose to ignore such simple instructions , but yes when it comes to changing oil the Super Tenere is an oddball.

I tried to follow the instructions. I believe and trust Yamaha. But the bike won't let me follow the rules. Oil light stays on without the entire jug. :oops:

I think it's important to be able to distinguish between rules that are made to stupid proof things vs specifications and procedures. Dry sumps cannot be overfilled realistically and wet sumps can easily be overfilled. If you understand how those systems work you understand why, and if you don't them you just fill it to the proper level.
As a commercial industrial havcr tech I do a lot of things that you "can't" do to get equipment working in emergency situations until parts come in.

I‘ve owned several S10s and stick with the 4000 mile USA spec bike oil change intervals while under warranty…….then, run 5000-6000 miles on an oil/filter change like the rest of the world. I’ve run several different oils in conjunction with Yamaha and HiFloFiltro oil filters. All is good.

I'm not an engineer, but I do have to ask myself how much of an engineering decision goes into motorcycle manufacturer's oil change interval.

How do they arrive at the 4000 mile number, knowing that an owner is liable to use any number of different brands of oil that still meet Yamaha's specs but have their own recommended oil change interval? If it was truly an engineering based decision, Yamaha would likely mandate that a specific brand of oil be used because that's what they based their tests on, and that 4000 mile interval was the result of actual testing. Or they would test several brands and mandate that those brands be used. But some oils, especially the synthetics, have change intervals that are markedly in excess of 4000; Amsoil's intervals start at almost 3 times Yamaha's recommendation. Does it make sense to follow Yamaha's recommendation if the oil manufacturer says their oil can be changed much less frequently? After all, it's a lot more likely that an oil manufacturer is conducting tests on their own specific product than Yamaha is testing every oil on the market that's JASO certified and meets Yamaha's specs.

Is that 4000 mile interval based on any probative testing, or is just a reasonable but arbitrary number?

I would ass-sume that if they were basing the mileage on an oil, it would be theirs. And I thought that on one of these oil threads, there were more than a few here that said they were actually going 6k between changes after getting oil report cards.

AmsOil says you can double the OEM interval. That's 8,000 miles. I will use the next test kit then. Maybe I'll have to make it a goal to get 8,000 miles on it before the first snow! That would be tough to do... but in the interest of science I can try!

Yes, I would agree. Besides the fuel dilution that is. Coming home doing the 1013 mile day most of thst was at 85 and going from 100 miles south of Boise to Rexburg was at 85 and thst was 500 miles and to maintain that with the load it was rung out with not a lot more oomph. I'll make sure the 8,000 on this oil won't be used like that to see if it makes a difference. I think it will.

Oil companies have always encouraged way more frequent than necessary oil changes mostly because it increases their profits.

Exactly, with engine machining quality going up, smaller tolerances= less blow by and oil tech getting better. I agree. Remember when Mobil 1 came out... they touted 25,000 mile oil change intervals for years and now.... you should change your oil per the manufacturer's stated interval. Why the change... could it be that their oil was being used in new cars leaving the factory and they'd sell more oil? I changed to synthetics after pulling several engines apart that had used synthetic oil. I couldn't believe the difference as they were clean. Not even gunked up! Oil drain passages were clean and open.
I am not trying to change peoples mind about which oil to use. Just had an opportunity to see what one oil was like at high miles and flogged. Now the next one will be at 8,000 with most likely much less flogging! I thought it would be interesting and enlightening instead of just opinion based.

The #1 thing that drives my oil changes is transmission feel. Most bikes I've had start having grumpy transmission feelings around 4k miles no matter what oil I use. My z900rs called for 7k mile intervals but past 4k the trans felt like it was full of marbles. I'm actually embarrassed by how bad that trans was but the bike overall was excellent.
