Oil grade

[janwer]

I'm searchnig for oil
It's easy find API SG or better because most engine oils is better.
Viscosity 10W-30 for non tropical tempteratures is quite rare, but still possible to find.
JASO MB is difficult to find in Poland. Most motorcycle oils is MA which is without friction reducing additives for wet clutch bikes. PCX has dry clutch, so absence friction reducing additives can affect fuel saving or engine life.
MB, 10W-30 and syntetic is impossible to find.
What kind of oils do you use and what are your experience after?
What autorised dealers using during service?

You don't need to use motorcycle oil in the PCX since it has a dry clutch -- any 10W30 synthetic will work fine. Since the temperature at warm is the 2nd number in the oil weight, you will also be fine with 5W30 if that is easier to find. Even 0W30 will probably work.

I moved this thread to the General subforum because of this post.

I just get the oil.
Honda 4-stroke motorcycle oil. API SJ 10W30 MB. 51 zł (12,5 EUR) / litre
Exactly as specified in manual.

£45 a gallon. Oof

Mind you if you are only buying a litre at time it isn't so bad

[janwer]

I plan to use it during warranty. Then I'll think again.

Not so easy.
The viscosity of 5w30 will be lower than 10w30 at operating temperature. The relationship is not linear.
Also 0w30, 5w30 and 10w30 have different characteristics as to how their viscosity changes over time. 10w30 is more stable than 5w30 because of smaller difference between the first and second number.

Also, amount of ZDP in motorcycle oil means it's safer for valves than comparable auto oil.

Hmm -- oil is always an argument on forums in general, so lets all be civil moving forward, please (not saying anyone is even nearing argument or anything, just trying to keep everyone happy).

Since the PCX has a dry clutch and CVT, any generic synthetic should be more than fine. You can use Honda oil, but I see no difference, and am 100% confident my PCX will be fine on Penzoil, Castrol, or whatever else I throw in there. If it had a wet clutch and transmission in the oil like most motorcycles do, the additives in motorcycle oil would be necessary.

Then what's with no energy saving oils?

I run Mobil 1 5W-30 in my car and obviously I have left overs from a service that adds up to at least enough to do a service on the PCX. Now I read that people put in whatever and it'd work but I'm just not confident just throwing in even Mobil 1 in there. My only option is to get the Honda HP4M semi synth oil which gives the price makes the even more expensive Mobil 1 0W-40 cheap. Actually quite torn by the oil decision myself.

Coincidence. I do exactly this. Same oil, same brand, same grade. Works perfectly.

I'm with you, in that I run Mobil 1 in my Honda cars, but the strict language in the owner and service manuals for the PCX create pause for me. I'm sure that just about any decent motor oil will do fine in the near term, but what about after 20k miles? The detergent agents in car motor oil may be the biggest difference. Mechanically, the unique aspects of the PCX engine are the smaller physical space and thus inability to take any foaming and of course the roller bearings. No modern car has those same constraints. Course, im sure there are other variables, but that is what comes to mind.

I've used only Honda HP4M in my 50cc Metropolitan since 2002. Overkill, probably. But after 11k miles, it still runs as smooth as when I bought it new!

[Inoplanetyanin]

Metropolitan (and probably PCX's) engine spins at 9000 rpm and has no filtering system.
This leads me to believe that it stresses the oil much more than your typical car, whose engine is spinning at a comfortable 2000-2500 at highway driving.

I personally use a 50/50 mix of 20W50 Valvoline 4 stroke Full Synthetic Motorcycle oil and Wal Mart's Super Tech 10W30 Full Synthetic auto oil. My metro has 16,400 miles oil it and runs just like when I bought it. Doesn't smoke, doesn't use oil, very smooth and quiet.

I also think in the long run, motorcycle oils are superior to automotive oils. I don't want to save few dollars when it might shorten the engine's service life.
