My scooter manuals recommend 10w-40 or 15w-40, I had 5w-30 synthetic on hand and used that for now. Some manuals day 5w30 is ok too. I didn't find 10w-40 synthetic at Walmart, there was 0w-40 and maybe 5w-40 synthetic, I think they had 10w-40 conventional, but not sure. I came across this www.walmart.com/ip/Mobil-Delvac-1300-Super-Heavy-Duty-Synthetic-Blend-Diesel-Engine-Oil-15W-40-1-gal/17034368It's rated API SN for gas engines as well as the C(something) for diesel. As a sanity check, if it says SN, it should be ok for gas engines, right? Also, should I be ok with the 5w-30 synthetic or should I rush to change the oil? I'm in virginia, just getting to 55 or 60 degree spring weather. --------------------------- Info I read elsewhere... If the diesel oil carries both specs, feel assured the oil is safe to use in diesel and gas applications. If the diesel oil does not carry the “S” category, I strongly recommend against using it in gasoline applications.
There are additives designed to manage the byproducts of combustion, and some of those byproducts change depending on whether you’re burning gasoline or diesel.
If you’re running a gasoline engine, it’s best to use an oil that contains the correct additives to handle the byproducts of gasoline combustion. The same holds if you’re operating a diesel engine.
If your gasoline engine is heavily modified to put out more horsepower, using a diesel oil can be beneficial.

The only oil I actually studied was Mercedes spec oil for vehicles equipped with a diesel particulate filter. They must must use a low ash specific oil. Different oils can cause the failure of the $3000 particulate filter in the exhaust. Ask me how I know.....

You could run that in the scoot if you really wanted to. The only drawback is most diesel oils will contain more detergents to clean the combustion contamination away. Would this be harmful to bearings long term?  Oil for gasoline cars is so cheap I don't really think it's worth the risk personally. |

Ok, I'll skip the diesel oils that are also API SN rated.
I found
mobil 1 10w40 full synthetic for high mileage
mobil 1 0w40 full synthetic european car formula
Same price, about $5 per quart
Any reason I should not get one of these?

Go with manufacturers spec weight oil. Bearings and seals are designed around a weight for lubricity and sealing properties.
What weight is recommended??
Of course these numbers assume no aftermarket parts have been swapped in.

Manual recommends several depending on weather, 10w40 as one option. They also say 5w50 is good for the wide (ambient) temperature range.
I think when the manual or scooter was made, 0w-xxx oil didn't exist. 10w would be safest, but I thought I'd ask to see if anyone knows about the 0w oils.

The 0W is mainly used in modern cars as a way to help emissions. It has very low friction. Probably only really useful in an engine designed to run lower oil pressure. You want a thicker oil as it will stick, and lubricant components more.
Both those Mobile 1 oils should be well above the requirements of a scooter. At the end of the day. These things are designed to be used in countries with poor gasoline and oil quality. And most never get serviced as they should.

Ok, thanks. I'll go for the 10w40 synthetic, it's not that expensive and may be more forgiving if something goes wrong. I'll add molly to it, too.

The first number after W is for 'Weather' or 'Winter' dependin on who ya ask. lower number before W will flow better when cold. SCOOTER LIKE HEAVY OIL. IT AIR COOLED. 40 WEIGHT OR 50 IN FL summer. first number irrelevant Also 'Motorcycle" oil is for wet clutch not really applicable to gy6. GY6's LOVE DIESEL TRUCK OIL. Diesel oil has added detergents and friction reduction modifiers. Cylinder walls sty clean and cooler. Multi viscosity service oil  thins out, breaks down, not designed for 400° scooter Truck oul has lead in init tho not good for catalytic converter in car. I use lots of cheap as dirt 13 dollar gallon straight weight 50 in my scoot loves it 💞 . |

I would use the Delvac or Rotella or Wally's SuperTech diesel 15W40 oil. Change regularly. It handles the sliding friction of the cam followers as it still contains the Zn additive previously available in most auto lubes.
The 0Wxx oils are designed to provide quick flow of lube upon startup no matter the ambient temperature.
I use the diesel rated oils. YMMwV. w==will.

I use rotella conventional oil for two oil changes after ring break in. I always use a break in specific oil for the ring break in than two regular changes with rotella than I switch to synthetic t6 rotella 15 40 or 15 50 I prefer the 50 especially with the synthetic bc it's a tad thinner. I beat the balls out my scoot u got 6500 miles from a Amazon 50mm bbk kit and it was still going strong when I rebuilt with a airsal piston and stroker. The stick crank was having no issues at the rebuild I just upgraded to a stroker. I never seem to burn any oil with the rotella where in other scoots before I was using rotella I always used a little oil even with new cylinders. I do believe fully in using a break in oil on a fresh cylinder and u use a hard break in. After about 50 miles once the cross hatch is diminished from the cylinder wall ur as broke in as ur gonna get. The hard break in spreads the rings against the cylinder walls and with the special break in oil u get a controlled wear between the cylinder and the rings. U believe that is one of the most important times of a fresh cylinder as the cross hatch acts kinda like a file against the rings wearing them in to the wall. Soon as there worn off the ring seat is over I've had great luck with that process
