The Honda PCX / Forza / ADV150 / SH Forums

I have just been speaking with my Honda Dealer's service centre, head mechanic and apparently i have been told... 'NEVER use fully synthetic in a honda PCX' apparently it need regular old dino oil.

Feel like banging my head against the wall... they make amazing bikes but some of their after service is stupid... my bike doesn't need good oil because its not a 180mph fireball (his exact words).

I probably would buy another honda again, from a different dealership.

So long as the oil is wet and slippery all will be well.
Does the manual recommend fully synthetic?

Or buy a 180mph fireball. Or fireblade. That wouldnt really need synthetic either really pottering around town

if you want synthetic in your scooter why not put some in yourself.

you have to take the old stuff out first but its only one bolt and there are some how tos here

We've discussed this before.

HP4M is a semi synthetic blend oil with moly that's recommended for scooters with dry clutches. Moly is extremely slippery and reduces friction providing better fuel economy and also produces less heat. Honda also says it can be used for motorcycles with wet clutches for racing in short periods, as long as the oil is drained and non moly oil put in after racing. The moly additive is great for optimum fuel efficiency and performance but not good for wet clutches.

HP4S is their full synthetic oil that doesn't contain moly. You may get slightly worse fuel economy and you'll get more heat produced although full synthetic oil stands up very well against heat.

I'd stick with HP4M unless you're continuously subjecting your engine to high RPMs all the time, and even then I'd just call HP4S a consideration.

Oops I have to add that synthetic oil has smaller molecules so it reduces friction that way.

So it's up to you. But to say synthetic can't be used is baloney (bologna?)

Can we settle on any oil can be used?

How's that extra virgin olive oil working for you?

I highly advise against coconut oil, you might have a hard time starting a cold engine.

Engine oil silly.

I would avoid using fully synthetic for cooking fries, but they would slide down well.

Reduces friction on what? Does the oil get onto the clutch or something? I would think that's a very bad thing that could glaze your clutch bell.

Sweet or savoury glaze?

Balsamic of course.

Not synthetic I hope

Moly will increase fuel econmy and reduce heat. Honda recommends using Moly ( HP4M) in the final drive as well , reduces heat , reduces friction from gears meshing . Call out to Cali. and talk to an engineer for the technical mumbo- jumbo , the number is in your owners manual. Ride well.

You're dealer is an idiot. The manual specifically recommends synthetic blend or equivalent, even during break-in. Full synthetic is ALWAYS better than dino oil, which is not an opinion, but a fact.

Your scooter will run on either, but will be happier over 10s of thousands of miles on synthetic. If you plan on keeping it for years and years, it's worth the extra $4 a quart.

Only after conformation takes place.
Which in some cases requires non-synthetic to be used initially.

On my main bike BMW prohibit synthetic but I used it after 10,000 miles with no problems.

I have run full synthetic in all of my vehicles for years now and they have given me many years of good service. My 2003 suv runs great. My Burgman 400 ran like new. Now my two pcx 150s just keep running without any problems. Yesterday we took them on the freeway and ran them wide open for 30 - 40 miles with no apparent ill effects. I change the oil on all of my vehicles at 3,000 mile intervals. If i have to stretch the oil a little bit later I doubt that there would be any problem with it because I use synthetic.

But they may have ran exactly the same on good quality oil of any persuasion

I think the main advantage is still stretching the change interval by using synthetic. The written warranty can affect its use, however. Some vehicles now require it in for cars leaving little choice. Conventional oil is slowly being replaced at the retailers.
