Amzoil 20w50 for me

OK, according to this artical above: in a Big Twin engine having no catalyic converter, no oxygen sensor, and the potentol to have high cyl. heat. high zinc quantities in oil is a good thing.

It doesn't specify big twins. I found another article and it again specifies flat tappet camshafts. I think since our engines are a sump its slightly different I think there is an issue with low levels of Zinc on "splash" areas...IE tops of engine. Since Camshaft is at the bottom of our engine its not quite as functional. But I imagine it can not hurt

Today’s engines are great at providing oil to every engine component except one —your camshaft. Windage trays,limiting oil’s ability to reachthe top of the engine,modification of connecting rod side clearances for lesssplash oil and special oil pans further complicate both the break-in process and camshaft operation in general.

Another note straight off Amsoil's website on their specifically designed ZROD formula for "flat tappets"

Protects Flat-Tappet Cams
The lifters and cam lobes on flat-tappet camshafts common to classic and high performance vehicles slide rapidly against one another, producing high friction and heat. The friction between the two components can eventually wear down the cam and affect valve operation, ultimately resulting in lost engine power and reduced efficiency. In addition, these areas are splash-lubricated rather than pressure lubricated like other areas of the engine, which adds extra strain on anti-wear additives like the zinc and phosphorus in zinc dialkyldithiophosphate (ZDDP).

If you are still sold on Zinc & Phosphorus, lets take a look at the oils.....

Mobil1 VTwin 20W50 - Zinc 1710 PPM
Amsoil 20W50 - Zinc 1434 PPM

Regarding the Schaefer Oil I could only get their analysis which states Zinc levels between 1600-2000. So you are in the range of Mobil1 in regards to Zinc levels.

Here is a great read on Motorcycle Oil's
http://www.superoilcentral.com/pdfs/motorcycle-oil-comparison.pdf

According to this study if you think Zinc is the secret ingredient you will want to pick up Maxima 4 Ultra which has 2100 PPM Zinc.

The study ranks the oils based on numerous criteria.
1. Amsoil - Wins by a large margin
2. Mobil 1
3. Maxima 4 Ultra

Thanks for posting the oil comparison pdf. It's a keeper.

"Protects Flat-Tappet Cams" Don't we have roller cams in our engines????

Yea, I found it while doing research and definatly saved it! Lots of good info in there.

Agreed, I think high Zinc levels are beneficial to flat-tappets although they do have benefits in oil period. However, looking through all the research I posted its clear that just having high levels of Zinc is not the only thing needed to make a good oil.

In the study I posted above it clearly states that the high levels of Zinc alone do not correlate to good wear protection

Quantity of zinc content alone does not indicate
its performance. Therefore, it cannot be assumed that oils with higher concentrations of zinc provide better wear protection.
Additional testing must be reviewed to determine an oil’s actual ability to prevent wear.The wear testing further in this document reflects the general lack of correlation between zinc levels and wear protection. Due to this lack of correlation, zinc levels are not included in the scoring and summary of results contained in the review.

IMO if you stick with the name brand stuff Amsoil, Mobil 1, etc your doing the best you possibly can to protect your engine. If something goes in your engine a different oil wouldn't have made it not go.

I agree, and will most than likely switch to Amsoil 20-50 MCV Synthetic. From everything on this thread, I don't think it can be beat!

I have been using Mobil 1 - Which is obviously a great product too.


I agree I think Amsoil gets great recommendations, and I have been meaning to try it. This research I did definatly points towards Amsoil as being #1. Glad I did it learned a lot

I think I may pick up a few qts of the straight 60 as well to run in the dog this summer. See if it cools it down

Just did my maintenance and stuck with regular high detergent Valvoline 20/50 with 1800 miles on it. Almost used Mobil 1 but decided to wait till my 3000 mile oil change. After reading that information that "Th3InfamousI" posted on comparisons of oil, I definately will use Synthetic, and most likely Mobil 1 because of it's availability.

Spectro in everything in it.

 

[K9PSYCH]

I use Amsoil in everything I own, 20W50 in the K9, 5W20 in my Ram & Challenger, & 5W30 in the Optima. I use Valvoline Maxlife in my 90 Jeep, due to the high miles when I purchased it. In the K9 & the 2 with Hemi's, it made the engine a lot less noisey.:zz2cents:

Engine ; amsoil

Spectro ; transmission

ATF ; primary

 

[Magoo]

Redline

X2 :2thumbs: Costs a little more but bikes run best on it. Would not even think of changing to any other!

 

[minermark]

Just got my two gallons of amsoil 20/50, cannot wait to get that redline shit outta my dog.....

 

[Tom Chop]

Amsoil in the engine and transmission. Spectro in the primary. I know I used to promote ATF, but after installing a Bandit clutch I`ve been following their recommendation of the Spectro for the clutch and it does lubricate the primary chain much better. As for the front forks the Amsiol 30 weight. Russel DOT 5 silicon for the brakes.

 

[liferider]

I can't find a distributer in North Louisiana for Amsoil. Anyone have a clue where it can be purchased?
