Motul 5100 4T 10W40 Semi-synthetic engine oil proved to be a very useful product for my Toros El Rio 50 4T scooter. The operation of the engine is stable. I recommend to other users.
The quality and grade of the oil in the positive very good oil at a reasonable price motorcycle runs and works well I use this oil from the beginning and do not complain so it is a matter of choice whether to buy cheaper oil of another brand or oil a little more expensive but better I do not promote the brand Motul. But I am simply expressing my opinion and opinions about this product.
Motul oils not only 5100 do very well I own both a quad and an enduro and in both this equipment and the other I pour Motul brand oils, they have very good properties, at a relatively low price, I have never had any problems with them. In addition, the bottle has a built-in funnel that makes it easy to pour the oil. I sincerely recommend :D
One of the best. A good oil for four-strokes. This bottle is interesting such a characteristic, solid cap, oil like oil, but any other oil, this one is one of the better ones, good oil is not bad. I will see it after 1500 km mileage. Motul this brand says it all. I will buy more than once, although this time I only needed 700ml.
I have been using valvoline oils for a long time like 15 years. I've been pouring oil into my moto for 2 years - oil according to the specification and suitable for the moto. Moto does not smoke, gears enter as they should, oil loss of about 200 ml / 6tys km is probably not much with the mileage of 76 thousand km.
For me it is ok.
