Why didn't Honda say pour in 4QT (A full gallon) instead of 3.9 qts in the engine oil capacity There must be a reason,(??)
I read many of you just pour in a full gallon, and ignore the 3.9 amount listed in the owner's service manual....
Doesn't that .1 actually over full the motor? (I know .1 doesn't sound like much oil (BUT) there has to be reason why(??)

I always assumed the difference was to fill the oil filter.

When you pour in 4 quart bottles of oil a small amount does stay in the empty bottle, times 4 equals 3.9 quarts no problem.

This has caused me many a sleepless night...LOL

Dump in the gallon/four qts and relax!!
Honda no doubt designed/built the engine and sump and then determined how much it would take to fill it by the liter and thus gave us a 3.9 qt fill amount.
My Wing goes up and down hills and leans around corners (condolences to those on trikes) which varies the oil level considerably so I assume the oil level isn't of paramount critical importance. If in doubt, check out what the oil level does in a bike with a sight glass oil level crankcase.

Why ask why?

But seriously, Honda was looking out for the “frequent flyers” of of the oil change hobby.

Honda marketing mavens decreed the oil refill amount should be “only” 3.9 quarts so the money you saved from that 0.1 quarts could go into your penny jar and saved up for your next Wing purchase.

3.9 is a lot better than 4.3😁

 

[Nodaker]

It's a metric bike built in a metric country so the actual oil capacity is some oddball amount in milliliters.

To give us another thread to weigh in on.

Honda says 3.9 quarts because that’s the correct amount. A very good mechanic once told me your Goldwing is probably the only one that comes in here not waaay over full of oil from people changing their own oil.

Best answer of the day........we'd really be bitchin' then.

 

[Arkyrider]

Honda wants us to feel good about them saving us money. After 11 oil changes, estimated, and based on 3.9 Qts, we will have enough oil left over equivalent to a free qt of oil.

Because quantity matters. If you add too much oil (even just a cup) it has the potential to make the oil froth (especially at higher RPMS) which can cause major engine damage. They specify 3.9 qts and not 4 because 3.9 is the correct amount.

You guy crack me up, I love all your come-backs

Thank you Fred, 3.9 Quarts (it will be always) ...I've been do'ing it correctly for years, on "both" my wings....

I found the oil level makes a big difference in shifting quality. I run my oil level at the lower mark on dipstick. High oil level got me nothing but rough shifts and ghost gears. Once I started doing the lower mark level, its not happened once.

 

[goldwing fan]

Yeah a real royal pain I just chuck in 4 litres of oil and be done with it

It was a marketing decision Tim? I’m speechless…

I designed and built an adjustable dipstick. Works great.
