Oil and Filter?

here is a little more info., i posted this in a different thread last year. hope it helps a little bit!


--------------------------------------------------------------------------------

the society of automotive engineers(SAE) have established 12 different viscosity grades. vicosity grades will determine the oils dynamic viscosity and kinematic viscosity.
the dynamic viscosity is the first # you see usually followed by a W , which , yes , you can associate that # with winter to help you think of how it performs in cold weather.the SAE has determined 6 grades of "winter" formulas beginning with 0W and working up to 25W in 5 point incriments. what they are measureing with this is the lubricants ability to pump 60,000centipointe units with no yield stress at certain temps. for ex.
0W = 60,000 cP @-40*C
5W = 60,000 cP @-35*C
10W = 60,000 cP @ -30*C and so on till 25Wwhich is 60,000 cP@-15
basically the smaller the # the better protection for colder temps.

the next # measures the lubricants ability to pour or its kinemetric viscosity, which is measured by the time it takes an oil to pour out of a container. the temp. is always consistant at 100*C (212*F)
this is #ered from 20 -60 in 10 pt incriments and is measured using sabolt universal second(sus) for ex.
sae20@100*c will empty in min.5.6sus and a max. of9.3sus
30 = 9.3sus - 12.5sus
40 = 12.5sus- 16.3sus
60 = 21.9sus - 26.1sus
in other words the oil will empty out of the container just by pouring in 5.6 seconds (roughly) to 9.3 seconds
remember you do not want your oil viscosity to thin in hot temps. because you will lose you ability to lubricate and protect your engine.

a good ex is this. a truck driver leaves florida with a load of oranges heading for minnesota, in fla. he runs SAE 30 oil because of the ambient temp. in fla. when he (or she) get to min. the driver finds the SAE 30 is to viscious or thick to handle the sub zero temps and is having a hard time starting the vehicle. after changing oil to an SAE 15W the starting problem is solved and he can continue on. when he gets back to fla. he finds the SAE 15W is to thin due to the high temps. in fla. therefore the lubricant can not protect the engine like it should.
thus they have made multi viscosity oils. the point is not that a certain oil is thicker or thinner because under different circumstances they will all flow the same it just depends on the temp. of the product.
hnow many times have we been in the north woods and the temp. has been -30* one day and 30* the next? i've seen it! make sure you choose an oil that is best for your climate and has a broad viscosity range to cover those sudden changes in weather!
basically the ultimate protection for any motor would be a 0W-60 but the viscosity range of that oil is nearly impossible to achieve
i run amsoil 0W-40 four stroke in mine and i love it!

next post on different comparitive tests run by the american petroleum institute(API) and exactly how and why an oil breaks down !

Somebody PM a price for the Amsoil filter and oil for a 2003 RX-1 Mtn. I might try if the price is reasonable.

price on the oil is $8.05 a quart//$95.40 for 12 quart case, basically 7.95 a quart that way little savings but not much.....filter is $14.75

The Wix Filter I found that fits my 03, 04 and 05 RX-1's is a WIX 51358

Awesome filter IMHO...

I would not run the fram filter it is junk. The Pure one is my first choice, then the super tech from walmart believe it or not is actually a pretty good filter then the Yamaha filter. Seen some of these filters all cut up and apart the fram is by far the worst one. I added a picture and you can see how crappy the fram filter is compared to the super tech from walmart. These are not the correct numbers for your sled this is just for a visual of filter quality.

Nice shot of the filters.

I think Ted Jannetty said it best in the FI forum...oil is like a religon use what you have faith in and don't push it on every one else! LOL I love that!

Here is a good link and look at oil filters and the reason I run a pure one. http://www.motorcycleinfo.calsci.com/FilterStudy.html

Here is a picture of how a good filter is made.

NAPA 1358 / AMSOIL 0W40

Take a look at NAPA 1358 above and it is the gold yet.

napa 1358 is wix 51358

The super tech from walmart is better than a lot of the more expensive filters not a bad choice at all. I will spend the extra cash for the pure one with all the extra pleating and longer filter media. That with 100% 0W-40 Amsoil and I am good for the winter. That Fram filter is a joke and I hope no one here runs it that was reason enough to post that picture.
