Title: Which oil do you use in your final drive?
Post by: Dennis on March 17, 2016, 09:39:18 AM
Hai,

there are a lot of different type of oil which can be used for the final drive.
I am curious which are used the most.

If you take a mineral oil, that could cause problems in an open system like the final drive.
Its said that the mineral oil is attracting moisture.
This will end up causing the oil to get like a sort of muck.
It even can come out of the final gear vent (hope I wrote it correct)

Hypoid gear oil SAE80 is what the workbook of Honda says.

GL-5 sae80 or the 80w/90.

I use full synthetic SAE 80w/90 (Gl-5)

Which one do you prefer and why?
The why i am very interested in.

Thanks for answering.

You must take into account that back in 1988/9 when the ST1100 was in the development stage that oils back then weren't what they are today. So suggested oil back then would have been near the top of the list from what was available.

I use SAE 80W/90 (better that straight 80) as it was left over from a diff change over on my previous AU Ford.

Added:- Oil is brand Castrol

I use the standard Pro Honda Hypoid Gear Oil SAE 80W90 in my 13.                :13Candy

I use 80/90, its tough stuff, a litre bottle will last for ever.

And there is no difference between EPX and SAE oil?

I cant find the difference between these two. Only thing I know, is that the same brand is selling epx as sae oil.

Thanks for you answers!

I don't know either Dennis - but the manufacturers recommended and branded bottle is about $13 or so, so don't spend too much time worrying that you can cause harm - basically - use what Brock has used for the last guzillion kms and you can't really go wrong.     :thumb

Hai,

thanks for your answer.
I think my english is causing some misunderstanding.

I am always looking for "knowledge".
Thats why I am asking.

I use the same oil as most of us. gl-5 80w90.

So its not about the money, but just to find out what yours opinion is on the other side of the world.

I did find out what the difference is between SAE (link -->CLICK HERE (http://www.sae.org/) ) and the EPX.
Only Castrol uses the term EPX so i guess that stands for something special in their oil.


Some interesting information which I found and which google translated  :thumbsup:

How can I recognize the quality of motor oil?
The quality of oil is indicated by international standards API and ACEA and standards of the vehicle manufacturer.

 
What is API?
API stands for American Petroleum Institute. This is an American institute, which indicate the quality of oils. API makes a distinction between gasoline engines and diesel engines.
• Petrol engines are indicated by the letter S.
• Diesel engines are marked with the letter C.
A second letter the quality level is indicated. With a few exceptions, the farther in the alphabet, the higher the quality. For example, a motor oil can have quality designation SL / CF.

 
What does ACEA on engine oil?
ACEA is a European standard and stands for Association des Constructeurs Européens d'Automobile either Association of European Automobile Manufacturers. The ACEA quality indication consists of a letter followed by a number.
ACEA distinguishes between petrol (display with letter A), light diesel (designation with letter B) diesel engines with a diesel particulate filter (designation by letter C) and heavy duty diesel (designation with the letter E).
With a number placed against the letter, the quality level is indicated. For example, an engine oil may be in the specification A3, B4, C3.

What is viscosity , and how can I recognize that a motor oil?
The thickness of an engine oil is an important value . This is indicated by the concept of viscosity , which depends on the temperature . Oil with a low viscosity is thin and oil with a high viscosity is thick .
SAE is the international institution that has set the standard for engine oil viscosity. The viscosity of engine oil is fixed at low and high temperature. Thus, the phrase becomes: SAE : 5W30 , 10W40, 15W40 , 20W50

The first number with the letter W : the lower the number, the thinner the oil at low temperatures ( important for cold starts) . The most common are : SAE : 0W , 5W , 10W , 15W , 20W .
The second number following the letter W : the higher the number the thicker the oil remains at high engine temperatures ( of interest in the summer). The most commonly used are : SAE 30 , 40, 50 . A general rule is that : the higher the SAE number, the higher the viscosity.


What is the advantage of synthetic motor oil ?
In the use of synthetic engine oil , there are a number of advantages:
• A synthetic engine oil has a lower resistance and fuel consumption is lower. Better fuel economy , of course, means a cost savings. Fuel economy is also better for our environment.
• A synthetic motor oil is thinner , making oil even when the cold starts , faster through will lubricate the engine. Due to the fast lubrication is greatly reduced engine wear.
• Synthetic motor oil provides stable thermal properties. This means that the oil longer and cope better against heavy load and therefore has a longer drain intervals . When you need to change your oil? This depends on the vehicle and type of engine. In the instruction booklet when to change the oil .

Is it harmful if oil is refilled from another brand ?
Not in principle, provided that the other oil quality level ( = equal specifications) and (preferably the same ) viscosity.

My knowledge about oil has went up  :grin

Dennis

Army OEP600 meant Oil Extreme Pressure and was used in truck differentials. Stunk really bad.

I wonder if EPX might be Extreme Pressure Xcross-linked

To my mind, there is no advantage to using synthetic in a diff. The tolerances arent that fine.

Winter grade may be of an advantage if you live in the snow, not so much a problem in Oz.

In the diff of the ST, there isnt too much stress. If you change the oil every year (20000ks or so) your bike will be fine.

Now put away the spanners and ride.
