But that is why everybody makes different weight oils. It is a common horsepower trick to use a lighter oil to get a few more HP on race cars, and has long been used by Nascar, F1 and Indy car racing. If you did not like a 15w50 or 20w50, then why not try a 10w40, which is in fact the recommended viscosity. Lighter oils tend to trade higher wear rates for better HP and fuel economy. Both Honda and Ford are going to 5w20 oils for better fuel economy. Oils and engines are getting better, so it is now possible to build a engine that will last 100k miles while using 5w20 oils. But I doubt you could get it to last 200k or 300k.....:) -----Original Message----- From: Boman, Jeff [mailto:[EMAIL PROTECTED]] Sent: Monday, December 09, 2002 12:32 PM To: [EMAIL PROTECTED] Subject: Re: Amsoil and D220 tires Jon, I've used the Rotella in my GTS for the past two years without any problems. Recently I switched to Mobil 1 10w30 (last two changes). My oil consumption is zero (is not measurable) with 42K on the motor. BTW, I did not like the perfomance of the bike using the Mobile 1 15w-50. It's hard to explain but the motor "felt" like it was "working too hard" with this thicker oil. Just my .02 worth.

Although it IS rated at API SJ and suitable for gas engines, it is a major step down in quality compared to the Amsoil, and is not synthetic. I use Amsoil 20w-50 (Series 2000) in my GTS, and I comsume about 4-8 oz in 3000 miles, depending on the mix of riding styles. The heaver I am on the throttle, the more it seems to use. However, this oil consumption is about 1/2 of what it was with Mobil 1 15w-50. If you want qood synthetic, but do not want to spend as much money, then try Amsoil Synthetic Heavy Duty 20w-50 or 10w-40, which used to be the top Amsoil product until the Series 2000 came out. This oil does not have any friction modifiers like the Series 2000/3000 labels, so if you are prone to clutch slippage problems due to oil, this would bypass that problem. There is both an Auto 20w-50 and a bike 20w-50, but I suspect it is actually the same product (and same cost). Retail the 20w-50 S2K is about $8.00, but the regular 20w-50 is $5.50 to $6.00. There is nothing special about Rotella compared to any other CD/SJ engine oil costing $1.50 a quart. In the test info I have seen, it comes in about mid-pack compared to its peers. PS: This fall, I did an oil change on my boat, which uses Amsoil S2000 20w-50. The oil was used for two seasons (2 years) for about 125 hours in my 430 hp 7.4 liter boat engine. I sent it in to a lab for oil analysis, and they reported far lower wear levels than normal for this engine, and I could have used the oil for another 50-75 hours. 125 hours in a boat is about the same as 12,500 miles in a car. -----Original Message----- From: Walter Garcen [mailto:[EMAIL PROTECTED]] Sent: Saturday, December 07, 2002 3:45 PM To: [EMAIL PROTECTED] Subject: Amsoil and D220 tires I've been meaning to post this to the list for a while: Tires: I put Dunlop D220's (120/70 F, 170/60 R) on my bike in September. I have put ~2300 miles on them since then. The front is slightly cupped, but nearly as much as the previous D207 was at similar mileage. The bike turns in quicker than with the D207 front/D205 rear combo I had before and definitely quicker than with the MeZ4's that were on the bike when I bought it (in all fairness those were nearly worn). I'm not keeping track of thread depth, but they seem to wear better than any other tire I've bought. I would buy them again. Amsoil: On my last oil change I put in Amsoil's "Series 2000 20W-50". I haven't tracked consumption from the date of the change, but I did track it since the satrt of my ride down Appalachia (Severn, MD to Macon, GA and back). In the last 2233 miles the bike consumed 16 oz of oil. which is almost half as much of what it was consuming before. Keep in mind this is more viscous than what I was using before (10W-40 or 20W-40). The oil is pricey and you still have to top it off every once in a while, so it's a cost/convenience tradeoff. Amsoil claims you can leave it in there longer (not that it would stay with the GTS1000's consumption, hehe) so it might be a wash. I'm going to try Shell Rotella 15-W40 in my next oil change ($6 to $8 a gallon locally). - Walt Garcen www.hvmparts.com The information contained in this e-mail including any attachments may constitute Corvis Corporation Proprietary Information that is subject to Non-Disclosure Agreement and cannot be disclosed to any other party without the express consent of Corvis Corporation.
