The Honda PCX / Forza / ADV150 / SH Forums

I am not losing my mind, I've posted about the same issue before and it looks like I am not the only one. I am at 6900 miles, the service is at 7500 miles. I checked my oil using the correct procedure in the service manual and the dipstick is not showing any oil reading.

There is no smoke from the exhaust. There are no oil leaks on the ground.

I have always filled the correct amount of oil. The oil is going somewhere. I am thinking of checking it every 1000 miles and whenever low use a turkey baster and add oil.

Make sure that its on the center stand..not the kick stand when checking

Sometimes my oil level will fall over time without showing any obvious leaks - I thought it was ok to loose a little over time just not too much.

Yes on centerstand, dipstick not screwed in, checked when hot and cold no difference. These engines definitely burn oil.

I think you'll find every manufacturer in the world will have something in the manual that their engine CAN burn some oil. At least every owners manual I've ever been read. And it's a broad swipe to say the PCX'S burn oil. Some do, but some don't.I've got a year and a half on my bike and I've never burned a drop. But if I start to burn oil, and it's a reasonable amount, I won't lose any sleep over it.

This is a good idea on any vehicle, not just the PCX.

Besides mechanical issues (stuck rings, leaking seals, etc), the type of oil (conventional vs synthetic) & viscosity will also play a roll in oil loss. As a general rule, conventional oils "burn off" more quickly than synthetics, and lighter viscosities do it more quickly than heavier ones. Changing oil type and/or grade might slow your visible loss?

Typical symptom of cylinder blowby. There will be many more users here who'll experience the very same thing in due time, some sooner then others. This all comes from the idea that starting your bike up and whacking on the throttle without allowing it to warm up properly is totally fine. It is just like smoking cigarettes It just takes time for the damage to accumulate into something perceptible. No big deal though you can easily fix this by getting either a big bore kit which is dirt cheap from Yuminashi or simply replace the piston rings and valve stem seals.

Exactly

Possibilities? ... only two at this point IMO

Someone is trying to sabotage your engine
OR
Improper initial engine break-in procedure
I would do an immediate compression check, rings are probably allowing abnormal blow by.

My PCX150 does not burn off oil at any noticeable rate between changes, its the coolant that can fall below limit in 5k.

Warm the engine, remove the spark plug, attach the tester and crank it 'til the gauge stops. Make sure you've got the throttle wide open when you do the test. I would have to read but I think compression should be between 150-160psi

I wouldn't worry too much, just check your oil more often. Oil might be getting into the combustion chamber through the evaporation plumbing. At high RPM engine oil will tend to go through their into the intake side of the engine and over a long ride noticeable oil consumption will occur. This type of oil consumption will occur with any engine when they are at high RPM for extended periods of time.

Amazing....I own 3 quality scoots and motorcycles and I always check the oil level before every ride. Takes 20 seconds and a paper towel. 20 seconds.
Change it 3 to 6 times more often than you do. Takes 1/2 hour and a qt of good oil.
Owners that gripe and refuse to look at a dipstick or oil window are amazing.
Amazing. 20 seconds.

Use synthetic oil instead of regular oil. Your engine will thank you. Even if you do or do not fix the oil problem, you should still need to use synthetic oil.

i can only check it in certain areas such as walmart only places i can find flat ground

Waste of time and natural resources.

Amazing.

^What's really amazing is your persistent uselessness and toxicity in almost every thread I've come across since joining this pretty awesome community.

^ OP listen to Gil! This is very true; however excess crankcase pressure from blowby will do the exact same thing. Especially in a motor were the break in was not done correctly like homie mentioned above. Either way it is not too big of a deal at the moment. Just keep checking the dipstick.

I have topped of the oil, when it comes to the 7500 service I will change to synthetic. I will check the level every 500 miles. The bike is used at wot often. I wasn't planning on changing the spark plug until 10k, then I'll have them do a compression check.

Sounds like a plan. If your not running synthetic but run at WOT often you are just burning a lower quality oil. I'd change it now and see how it goes.

Mel, why synthetic? There's a link to a break in proceedure that recocmends Dino oil for a thousand or so US miles. I plan on changing to synthetic at around 1600 US miles.

Yep, mineral oil is best for break-in, then switch to full synthetic.
