While at my local Yamaha dealers today during my weekly drooling session there, I asked the Yama-guru what he thought about Synthetic oil for the Majesty. Everybody within ear shot says NO NO NO ! They said the engine would start smoking over time. Has anyone tried it in their Scoot?

I've heard a lot of pros for it but I'm not quite ready to try it on my baby.

There have been many long discussions on this subjest over on the yahoo majesty group.

The general feeling is that with the majesty not being a very high performance machine, and with such short oil change intervals, that the extra expense of synthetics is probably not warranted.

A good quality dino oil, changed every 5000km, still looks really clean when it comes out, so i personally can't see the point in spending the extra $ on fully synthetic oil.

I use a semi synthetic blend in mine (Motul 15w / 40).
it's cheaper than the fully synthetic oils, but does a great job (for me).

In the end, i guess the decision is up to the individual.
as for the smoking ! that seems to me to be a ridiculous statement.
if that were the case, it would cause all engines to do the same, and as a side note, there would be a BIG WARNING in the yamaha majesty owners manual about not using synthetic oils.

Since no such warning exists, that means that yamaha has considered the possibility that some owners might use synthetics, and not had a problem with it.

Sorry for the long winded reply.

Thanks Jason for your input.

I have been reading most of the evening about the differences between petroleum & synthetic oils. And what I am learning is that as for the Motorcycle companies own oil, IE Yamalube, etc, it's just hype that the "motorcycle oil" is best for motorcycles. One really informative site about oil is http://www.pelicanparts.com/techarticles/mult_gas_and_oil/mult_synthetic_faq.htm. I agree, I can much easier afford the "natural" stuff.

And I read that synthetic oil is by far a more stable and just all around better oil than petroleum. It is used in 100% of the jet engines around the world because of it's lubrication qualities and tolerance to high heat.

But for us with scooters, I agree with you and that is to stay with the regular stuff. (Automotive) oil.

It costs so little to change it and so little time is required.

I use Synthetic oil 10w30 in everything I own, I buy it in bulk and take whats left and use it for my scooter or mower. The Yamaha shop told me "being a dry clutch that Synthetic oil like Mobile 1 would work great" I've never had a oil burning problem but I change my oil like clock work.

Rob,

How often do you change your oil. Using Synthetic oil, do you go longer between changes ?

Thanks !

I change the oil and filter every 3000mi, because of the oil change indicator and peace of mind but I live in Florida very sandy, dusty conditions not to mention with my wife and I we max out the weight limit on it. I worked at a Tire Lube Express and doing oil changes every day you could see the difference between the Syn and dino oils VS miles. But every thing else I drive I change it every 5000 mi and never had a oil related problem. I think if you drive under good conditions the dino oil for 3000mi is fine or Syn for 5000mi under the same conditions is fine. But for my conditions I need a little extra protection.

I want to use synthetic oil. I am at 600 miles. Should I use synthetic oil now at the 600 mile oil change or go with regular oil(probably Gastrol 10W30) for another round and then put synthetic in?

Thanks

Well, I changed my oil today and put in two quarts of Mobile 1, 10W30 and a new oil filter. I am about to turn over 6,000 miles. My Majesty has more vibration now than it did when it was new. After I came home from my 2400 round trip to Texas I noticed it. The Yama-guru guys at my Dealership said it wasn't anything to worry about. Well, if it's gonna throw a rod or something, I'm going to do my best to do it while in warranty. Other than that, it continues to impress me.

I am thinking I'll go 5,000 miles before the next oil change. What say ye?

I would use regular oil till you hit 1500miles then switch to full synthetic oil, then change your oil in accordance with the warranty. I myself change it every 3000 just because I like the oil change reminder. I also installed a magnet on the oil plug to get any metal in the oil pan. So far very very happy !

I switched to Amsoil 10w40 full synthetic for motorcycles in the motor and tranny at 7,000 miles. Changed the oil filter. Runs great so far, and since the oil filter is only due every 12.5 thousand miles, I might go half that way on this oil. I will keep checking it though for signs of getting dirty or smelling funny. Since the scoot does not have a transmission that share the motor oil, the alleged effect of auto synthetics should have no negative impact.

I have read that it is a good idea to use it in the rear end, and it is less viscous than dino... any thoughts?

viscosity (sp?) is what ever the label says, wether it's dino oil or not.

so a 10w/30 should be a 10w/30 weight if that's what's on the label.
dino or not.

the biggest differences are that the synthetics are supposed to deliver better protection under extreme temp and pressure conditions.

I am looking for Amsoil stuff for my majesty and the Amsoil web site is not helpful at all. We need someplace where we can post the various part numbers and such for these high performance oil products and filters so that we could look and then call an amsoil dealer. That stuff works great and is better on the fuel economy too. What part numbers and such do you have? Thanks

I would agree with synthetic, except that Yamaha went through the trouble to specifically post a warning in the owner's manual against using "better than specified" oil.

I would tend to believe Yamaha. If they sold a synthetic oil for $10/qt., I'd use it. They don't, and I won't.

I would love to see the logic behind the warning to not use better oil ... seems rather un-Spock-like to me. There is no clutch or tranny mixing with the oil, so the argument there is effectively eliminated.

Amsoil is less than $10/qt ... do you mean Yamalube full synthetic for less than $10/qt?

I run dino in the crank, and synth in the gears. I change my oil twice as often as specified, so not really any point in using synthetics.

I prefer to do less maintenance, not more ... that is why I bought the Majesty in the first place. So it turns out your oil costs are as much as mine with fully synthetic and we are probably getting about the same protection unless you drive in extremely dusty conditions. That would certainly benefit from more frequent changes.

Hey, there is nothing wrong with using more oil ... its only a non-renewable resource.

I haven't had my new Maj on the road enough yet to change the oil, but when I do, it will be synthetic. I put 23,000 miles on a Honda Reflex (traded for the Maj400). I changed the oil every 1,000 miles to keep the little motor in like-new condition, and I always used Mobil Synthetic. It's very reasonably priced at Wally-World, and the Reflex uses only 1 quart. I never had any detectable engine wear or oil consumption. I plan to continue to use the Mobil Synthetic in my Maj. I notice the harsh cold-cranking sound when I crank the Maj in cold weather. I do not expect to hear that with synthetic. Also, there is more to oil degradation than mere loss of viscosity. You also get a subtle abrasion effect from the by-products of ignition, regardless of viscosity. I'll stay with the synthetic and with the 1,000-mile changes. I believe it's worth it to keep the little mill in pristine top shape. I was impressed with the info on synthetics on the "pelican" website (cited in the posting above), and it reinforced my position. Thanks, everyone, for your participation in this forum.

I'm with you Wayne
When I purchased my 1995 GoldWing & as soon as the break in oil was out of there I put in Mobile 1 15/50 Synthtic. At 99.000 trouble free miles I traded it for a 650 Burgman. The engine was still clean & was not using any oil.
My Burgman has this oil in it today.
Same when I purchased my 01 Reflex new. Breakin oil out & in with the Mobile 1. Put 7.000 miles on it, then I traded for a new 05 Majesty that shares the same oil story.
Funny though. For my toys I use the expnsive oils to preserve its engine life.
Yet in my cages i use the cheap chit!! :twisted:

Lou
05 Majesty Mini Trike
05 Silver Bullet Burgman 650
And one old Buick that just refuses to die! 200.000 miles & going strong.
