Has anyone noticed a difference in how your PCX runs with regular gas instead of premium?

I just put premium in cause it's only like 0.40 extra a fillup

No difference, I used to put premium(91) in, now using regular(87)... saving a fortune

Manual says 86 octane or higher.

My gas is never regular.....

No difference to me. Manual calls for regular.

The only difference is the money you spend on premium. Save your money for something else. Like valve clearance checks....

Yeah I will switch back to regular. Notice no increase in mpg after three fillups. Still getting around 80mpg

The tank is small enough to the point where it'll only cost a little extra to put premium. If you're really stretching your wallet and can't afford that then don't do it. I don't see anything wrong with treating your baby to premium if you can afford it.

Won't hurt using premium but, won't help either.

I just switched from regular to Premium because the ethanol in the regular was making my scooter run erratic at times. If I find a station selling regular that does not have ethanol in it I put that in it. Same thing was happening with my Burgman. This is what my Burgman book says I should use:

FUEL (FOR USA AND CANADA)
Use only unleaded gasoline of at least 87 pump octane ((R + M)/2 ) or 91 octane or higher rated by the research method.
Gasoline containing MTBE (Methyl Tertiary Butyl Ether), less than 10% ethanol, or less than 5% methanol with appropriate cosolvents and corrosion inhibitor is permissible.
FUEL (FOR OTHER COUNTRIES)
Gasoline used should be graded 91 octane (Research Method) or higher. Unleaded gasoline is recommended

Well, I have tried Premium, Mid-Grade, and Regular, and this last time put non-ethonol 90 octane and have not noticed any real differences. Maybe (maybe) 2 more mpg with the non-ethonol, but that is not enough to really say there is a definitive difference. I am only getting 72-75 mpg with mine. I drive 55 mph and a good bit of hills, so I have never seen the 90-100 mpg range many are getting with theirs. I wonder what a Forza would get me with the same trips...

Hi all. I've been checking out the board for a while and waiting for my new PCX to arrive. My current SYM VS150 seems to like 95 RON however still goes well on 91 and 98 when i decide to use either.

In all the bikes I have owned over the years fuel octane rarely any noticable difference in power however I have found (maybe just a mental perception) that higher octane seems to run smoother/cleaner. I'm no petro-expert so might just be imagination. This may be more down to the lesser likelihood of bad quality premium fuel?

There is also the quality of fuels available. Finding a servo that sells and maintains GOOD QUALITY fuel of any type from 91-98 OCTANE is more important to me that using a specific RON rating. I haven't found a way to check the quality of fuel before so it's anyone's guess.

Air humidity, temperature, pressure all have a factor in how clean our engine's run.

I discovered that it is much better for the item involved to be left to the professionals who have the time, training and the tools to do the job right the first time with out breaking anything after the first few minutes of the endeavor. Such things can be bloody expensive.

Different people do have different levels of competency, funding and naivety.

Guess so. A valve adjustment is easy, especially with the pictorial how-to.

maddiedog can we ad the specs for the pcx 150 into the how-to. The senior mechanic at my local dealer (30+ years of working on Honda bikes) showed me the spec in his book to be (erroneous, removed. Proper spec in how-to) for the exhaust specs.

For the sake of balance can I do a pictorial how to of not bothering checking them?

You just need a picture of kneeling next to the bike with your ear against the bodywork under the front of the seat and then one more picture of you waving it off kneeling next to the scooter.
Done.

One picture more? In the pub with a pint and an unworried look?
