C5 Oil

Mobil 1, Royal Purple, Valvoline....all to close to call a winner. As long as its synthetic oil.

=====================================================

Hope this helps

An article I just read humbly suggested that interested parties get the August issue of Sport Rider magazine (which has a detailed definition and explanation of the additives and compounds used in various motor oils), and the October issue on newsstands now (where chemical analysis of various brand oils was performed, along with various lab tests, plus a dyno test of dino vs. racing synthetic).

Enjoy your ride,
Gary


PS.
Interesting web site on the subject... http://www.bobistheoilguy.com/index.html

Gary, I read the same article. Since I have a dry clutch in my K1200RS, I am going with straight automotive Mobil I in my bike, also. Anyone in the aviation industry knows that an AD (airworthiness directive) came out on some lycoming IO360 engines that requires the use of an additive to prevent premature wear on the camshaft. I think the Shell oil has an oil with the additive already mixed in for those owners. The point being that oil stock and additives can and DO make a difference. Mobil 1 has never been reported to be problem (AFIK), is recommended by the factory, and is easily accesible for me. Mobil 1 is in everything I own. If there is something else comparable, I don't really care.

The wife has a BMW 325XI. The first time I got an oil filter cartridge in early 2004, (yeah, just the guts- no outer case!) The counter man at the BMW parts dept. offered to sell me the BMW full synthetic 5W30. I hesitated and asked how much are you getting for a qt.? He said $3.80 and said that it was made by Castrol. If you look under the hood of my wife's 2003 Bimmer, the oil filler cap says "BMW recommends Castrol" right on it.

I have had good luck with both Mobil 1 and Castrol with several different cars I've owned. I'd say I got slightly better mileage with Castrol over the long run. I calculate mileage at every fillup. I average 21 mpg. on my first generation LS1.

If you change your oil like I do at about 4000 mile intervals, the savings do add up, and both are premium products. The BMW oil is now $4.00/qt. while at Autozone, and Advance A P the Mobil 1 is like $5.60. At really 7 qt. an oil change, you save about $11.20 a change or $33.60/yr. if you drive 12,000 miles a year. That $ can go towards the never ending MODs budget, thanks to Eckeler's, Corvette Central, Mid America, etc.

Just a cheap old Yankee's opinion

Hi ,Please consider Amsoil 10w/30w synthetic go to there web site
www.amsoil.com and read there research on mobil 1 oil I think you will like it. They were the first in synthetic oils eliminates the sewing machine sound (lifter noise on start up) due to the oils adhesion properties. I have been using it in my oil cooled V Twin Motorcycle for 5 years it runs cooler and quieter as well a little better gas milage too ....Dr C5

About 4 years ago there was a law suit lost by Mobil1. They sued because other synthetic oils were saying that they were fully synthetic when in fact they were not and used up to 50% fossil oil. Mobil1 is 100% synthetic the others are not. The only one I do not know about is Royal Purple. I'm sticken with Mobil1..just my $.02...

Finally, something we can all look at to compare our synthetic oil concerns with. The site is http://www.amsoil.com/ and my two month search has just been confirmed about many specific brands... thank you Dr. C5.

For those of us who prefer not to take the time to do the research, you have good reason to be content with Mobil 1 and I feel better about the Chev/Mobil Politics. But for me, I will take the final step and go with the oil that performed the best in every test.

Thanks again Dr C5,
Gary
