    Remember the good ol days when this was this stuff was cheap? The Varadero and quad will have to do without this year.

    Rotella T6 fully synthetic 5W40 is on sale at Cdn Tire right now - next 3 days only.
    $125 for 19 litres. Plus rebate from manufacturer. You can afford to give them all a drink.

    I loaded up on Pennzoil Platnum Synthetic 0w20 a few months back when Wal Mart had it on sale for $28 a jug. My Toyota Tundra takes > 8 liters so that oil change gets expensive fast at the regular prices of ~ $50 a jug.

    The Tenere gets regular old Yamalube dino oil so I just buy that whenever. I always try to have a gallon of oil and filter on hand at all times tho just in case. I remember a time when I would change it every fall before storage (regardless of mileage) just because the internet said so. Well that hurt my wallet after awhile so that had to go! Now it gets changed when the mileage is due and not before.

    The Yamaha Grizzly hasn’t had an oil change in at least 2 yrs, won’t be getting one this year either.

    Honestly, I have no idea when I changed the oil in my quad...but I swap out the gas once a year, haven’t used the quad in 2-3 years. Well...the quad oil is cheaper....so maybe I’ll treat it with some oil. The varadero can wait another year, lol.

    I don't get too fussed about putting the bike away with new oil. If it is due for a change (or nearly) I will do it but leave it for the spring if there is less than maybe 4000 km on it. My bike takes 4 litres when I change it although capacity from dry is around 5 L. No matter what, you still have 20% old oil anyway.

    I like to change the oil before storage. Id rather have fresh oil on the engine parts. It’s gotta get changed anyway.....why wait for spring, do it now. I think that’s a TV commercial, lol.

    Both of my motorcycle’s Owners Manuals call for the oil to be changed at least once a year, regardless of mileage.
    Lucky for me, the oil has been getting changed based on mileage ever since I retired, as I am averaging around 10,000 miles per year, per bike. With that said, oils collect a lot of moisture while sitting in storage. I would think that it would be better to change the oil annually with an inexpensive store brand oil, than to not change it at all...

    I used to do the fall oil/filter change religiously. As the bike (and I) got older, I thought,why do I want new sitting and collecting moisture over the winter? I will do an oil/filter change after the first engine warm up of the spring. Not the March "OMG I need to hear my engine run!" warm up, but the mid-April, "I need to get the bike out of the shed!" warm up. That's actually well before our spring though lol.

    What's the difference between having somewhat used oil in the crankcase between rides all season long and having similarly used oil in the bike during the winter layoff?

    I figure I did my last oil change for the season today. Filter too (every second oil change as per Yamaha). Probably won't get more than a couple thousand km between now and when they start with the road salt - anywhere from early November to mid-December. I don't take it out with salt on the road - too much corrosion damage possible. Fairly disappointing season for me - 22,000 km so far which is the least I have done in the last dozen years. Unlikely to make 25,000 unless we have a miraculously extended autumn.

    For the last ride, I try to make it a couple of hours to blow any residual moisture out of the oil and exhaust system. After cooling, plastic bags get rubber-banded over the mufflers to prevent moisture ingress and I throw a cover over the bike to keep the dust off. Don't have problems with rodents so I don't have to take any measures to keep them out of the airbox, wiring or upholstery.

    No battery tender but the battery gets a slow top-off charge a couple or three times between November and the end of March. (Got 10 years and ~250,000 km out of my last battery.)

    I really need to do some fairly major maintenance including a valve check, front fork fluid change, rear Penske shock rebuild, brake/clutch hydraulic fluid and some electrical rewiring I have been postponing all season. All will probably wait for Spring.

    I read this on the internet:

    "As the engine operates, acidic by-products from the combustion process get past the piston rings and into the oil. The acids combine with moisture (every gallon of gasoline burnt produces 1/2 gallon of moisture) which can dissolve bearing surfaces.
    Modern motor oils contain additives to combat the acid build up in the oil. As the oil becomes contaminated and turns acidic, the additives get used up. Preventing acid buildup is a very big reason for changing motor oil regularly."

    For me, I'll add fresh oil before winter storage rather than keeping the dirty and possibly acidic oil in the engine. Plus keeps the bike in 'ready to race' mode in the event of a nice winter day.

    My point was that the moisture and "acids" are there anyway - whether the bike is being ridden regularly or not. I suppose having the clean oil in there during the off season means that the supposed corrosion isn't going on while the bike is idle and waiting for spring. I also feel better putting it away with reasonably fresh oil too but I'm not going to dump 4 L of fresh synthetic with less than 2,000 km on it just to satisfy some internet "Wisdom" on acidic combustion by-products in my oil. Very little moisture should be present anyway if you gave it a decent run before putting it away.

    Modern oil is pretty good stuff. The Black Magic additive packages tend to maintain a benign chemical environment in your engine. Engine metallurgy is also a lot better now than it was 25 years ago. Remember when a motorcycle engine needed to be rebuilt by 50,000 miles (80,000 km)? Had almost 4 times that on my last bike and never touched the engine except for plugs and a couple of valve adjustments (and it still didn't burn a drop of oil when I sold it).

    I don't think anyone suggested changing relatively fresh oil.

    Sorry - not arguing, just furthering the discussion a bit. (And stating MY practice and justification.) Absolutely not preaching about the "right" way to do anything but I have a pretty good foundation in chemistry and electrical stuff and can sometimes help... I also do stuff because it makes me feel better about something even though (intellectually) I might know it doesn't make any difference. On the other hand, I almost take pride in the fact that I almost NEVER change drain bolt crush washers despite manufacturers recommendation (never had a drip). Also never changed tire valve stems from OEM on my last bike in 10 years despite people telling me to change them with every tire change - always checked them and no leaks or apparent deterioration. (The last thing was probably pretty dumb but I got away with it.)

    Was making a bit of a point about some of the Internet "Wisdom" we all encounter from time to time - I have had people tell me that not putting fresh oil in for the winter will dissolve my engine internals. The same guys that tell me my battery will be destroyed if I don't put it on a tender daily (never do), that I should use a K&N filter for better power, that I must use a MC specific oil (almost never), and that I ruined my engine because I didn't do a "Motorman" break-in.

    Speaking of batteries, the battery in my WR250x was 9 years old when I replaced it. It stayed in the bike in an unheated garage and got charged once a month during the winter. I only replaced it because I thought it was about time to so. I still have the old one and use it to power a small air compressor when adjusting tire pressure.
