I am not sure with the 2 valve engines but I know the 4 valve seems to need the right oil. I buy a gallon of the stuff in advance and then store it until I am ready to change the oil. That way I always have what I need.
A&S in Sacramento carries 10/60.Elk grove carries Motul 10/60 which is what I use.Also I've bought from these guys. IIRC they charge a flat rate shipping of 7 or 8 bucks.http://www.racerpartswholesale.com/product/11024/Motor_OilsAlso any BMW auto shop carries it.Or lastly...Any NAPA can order it for ya.Edit...Hey I see that Kirk and the Gorn buy from racerparts also.Quick...who played the Gorn?
I bought a case of Agip 10-60 from these guys:http://www.motocarr.com/Shipped to my door it was still cheaper than 20-50 Mobil 1 from AutoZone.
How long do you guys go between changes? Does this oil keep viscosity over a long service life? Or do you still change oil every 2000 miles?
When I bought my MV I looked high and low for Agip 10/60.
Personally I'm glad I make enough money to spend $100 on a case of the proper spec oil and not worry about it.
People can be funny creatures. If you can convince them that they will surely be struck by lightning if they don't do "X" or purchace "Y", they will not only line your pocket by buying the product, but do their best to brainwash their friends into doing the same. Is this a killer business plan, or what?In the computer world, it's taken as gospel that unless you protect your computer with the very latest virus protection programs, your hard drive will be reduces to smoking slag in a matter of seconds. Some claims go even farther. One highly advertised product claims that their program "finds and fixes the problems with your PC". I remember reading a product evaluation for this product on one of the Geek sites where the geek purchased the product and loaded it into his well-used PC> The product identified and corrected 426 different problems in a matter of minutes. He then loaded the same product into a brand new computer with a never used hard drive. Result? In a matter of minutes, it found and corrected 426 different problems. What I'm trying to say here is that some manufactorers prey on the consuming public. I have an old PC that I have ran for years without any sort of protection of any kind... and it's still working. Hasn't burned the house down or anything.As to oil- a good example can be made regarding the Russian motorcycle I own. According to the manual, it requires premium gas with a minimum of 91 octane. This in an engine with 7.5-1 compression and producing a whopping 40-45 horsepower. Why is this? Well- when the importer was jumping through the hoops placed in front of it by the EPA, they had to do everything they could to get the primative design to pass emissions, and they chose premimum fuel because it gave them the advantage of running a leaner mixture without pinging. Since the emissions were certified using premimum fuel, premimum was what they had to specify. The oil they mandate is SAE 20w-50. That's what they used to pass emissions. That's what the manual calls for. Of course, if you watch the "how to do minor maintenance" video they offer, it sure looked like Cheveron SAE 30 they were pouring in. Lightly loaded, all roller bearing engine with a 1700 mile service cycle? That's all that's needed. There are certain applications which do require better lubrication- applications where the exhaust valve is cooled by oil, for example. There, MG specs a 10w-60 oil. They probably also like the idea of having a little greater protection as insurance against warranty claims. The funny thing is- the viscosity has absolutely nothing to do with how an oil will react to heat. Folks who've spent some time around air cooled VW's can attest to this. You could always tell when someone was using Penzoil because the parafin-based oil broke down into greenish crud when faced with the oil temps generated by the air cooled VW. In a water cooled Buick V8 it was never an issue. As I see it, unless the application actually demands some super-lubricant, it's probably a waste of money to slavishly use it. Just like it's a waste of money to put premimum gas in my old Ural. Been running regular for six years and never had an issue.PeteT.
I give up. Who did play the Gorn?
I don't think the fuel analogy holds any water either. At the very least you'd need to find out what oil recommendations they make in different markets (away from EPA or EU control) to know if you've got anything to base it on.Also the comments on marketing miss the target. Though I'm sure there is a relationship between Piaggio and AGIP, it's not like AGIP is the only possible source of oils that meet their recommendations.
