I am about to do my first oil change. I have a link to the engine manual for the linhai yamaha clone 250.

It says to not use any oil with additives because the oil also lubricates the clutch and additives may cause slippage.

ANy way, I bought castrol 4 stroke motorcycle oil 10W-40 thinking it would be good. Got home and it says it has "specialized additive package that contains antioxidants, detergents, dispersants and varnish inhibitors that help prevenbt ring-sticking and build up of harmful engine deposits". Should I use this or will it hurt my 54B?

Hi Mcalli. That instruction with the warning about oil additives is for motorcycles which use a wet clutch which uses the same oil as the engine. Does not apply to our scoots since we have CVTs which have dry clutches which are separate from the engine. All modern oils have additives. Additives are necessary to make the base oil into a multi-viscosity like 10W-40. Additives are added to keep the engine clean and also to improve lubricating qualities. The type of additive package used in some oils might affect the performance of a wet clutch which is not used in your scoot or any scoot with a CVT.

The Castrol oil you bought is fine for your scoot as well as motorcycles.

Thank you cruiser. You know, there are definitely some advantages to being male. I cannot do my oil change, not that I don't know how from the diagrams and specs. I have my ratchet wrench but I do not have the strength to loosen the plug for the oil change. I have tried and tried and it just won't budge. I don't have the strength. So, until I can get my son-in-law (who isn't home right now) or a male neighbor to make that initial turn and loosen that bolt, I am stuck. Oh well I will just have to live with being "the weaker sex". I have to live with it, but I don't have to like it.
(I think they crazy glued that bolt on)

The oil you have is perfect for your scooter. It can handle high rpms and higher temperature's as well. Under the bolt to remove the oil is a spring and a small filter. The spring does put tension on the bolt so it can seem harder to remove. Are you using a 19mm socket with a 3/8" ratchet?

I use the Castrol 4T 10w40 oil in my Vog. It takes exactly 1-1/2 quarts. (It's actually 1.4L or 5.92 cups or 47.34 ounces, but 6 cups is 1-1/2 quarts). Heh. I just buy 3 quarts at a time and I know I'm good for 2 oil changes. When you take out that big drain plug, a cone shaped screen should come out with it, if it doesn't, reach a finger in there and pull it out. I let mine drain for an hour because I like to get as much of the old stuff out as I can, or I will waste a little bit of fresh oil and pour just a bit into the filler while the drain is open to flush it a bit.

For the gear lube I use Mobil 1 LS 75W-90 - (.25L or 8.45 ounces)

I have 2 plastic measuring cups I keep in the garage for this, along with skinny funnels that will fit in both filler holes.

yes, it was very tight. I finally got it loose.

On difficult nuts, if you have a little room, once your ratchet is on the nut, find a piece of pipe about 12-18 inches long and slide it over the handle of your ratchet (effectively extending the length of the ratchet handle). You will be amazed at how much additional force this will generate at the nut, without having to push any harder than you have been pushing. Nuts that I have sweated and strained over come off easily this way. The longer the pipe, the more force you will be able to generate.

I have two college age daughters, and in each one of their cars I have place a two foot piece of pipe to slide over the lug nut wrench for just this reason, in case they need to change a flat.

Sometimes, physics is our friend...

philosophydoc is soo right.. With the pipe thing. Some of us guys call it a breaker bar to sound more manly I guess. Anyway next time try his trick I can assure you it will work.

[sunlproblems]

or if u dont have a pipe use a socket and extention as the cheater bar it works great do it all the time
