Using Torco SR-1 20/50
About RM67 / litre, we use around 4.5litres (5bottles @ RM335)
Oil filter RM35 (Mitsubishi)

That the basic oil change maintenance every 5,000km - 7,000km.

Most branded fluids are good for the ride.
If talk about Motul itself, is very competitive product in the market.
Due to several viscosity & other type of fluids could reach.

Viscosity depends on the engine spec & driving.
Myself using 5W-40 if the ride drive by family member in town ride.
Or 10W-40 for long distance ride....
If Spirited ride for the whole day I will use 15W-50...
Most of the time I stay on 10W-40 due to use only long distance & smooth journey.

For those are modded especially internal part...
Normally they will use 15W-50 or higher.
While on thicker viscosity it need longer time to warm up the engine.

Check your Engine Oil Temp from time to time if the fluids suitable for your driving or not.

I use MOTUL for almost everything except AYC fluids stick on Diaqueen...

What do u all think about this lubrication oil brand jtx1000,i saw it on this link:
Ujian Keberkesanan Minyak Enjin JTX1000 - YouTube
It is SAE 15-50w,my friend of mine already used inside his 350whp evo7

im using motul 6100 10w40 for normal daily use, or change to 300V for track days.

so far, those two are the best oil so far for my car..tried Sumo R1, Q8 before..temperature wise better with Motul for my car.

how about Eneos 10w-40? i dare not to pour thicker oil as the manual stated 4g63 runs fine with 5w30 or 10w40.

5W 40 i m using
10W 40 is ok. Not too thick for daily driving. Do used the search function as we already discuss this few times in this forum

[yihao88]

60 very thick la Yap. if long distance and track ok lah.

Reli?? Too thick is a burden for the engine??

 

[lanevo6]

Reli?? Too thick is a burden for the engine??

not burden or cannot use. Just that when the oil is too thick it's a bit heavy/sluggish or slower to respond. Try change to 40 and see if you can feel the diff......if not then u can stick with 50 or 60

just want to share great info with ya guys. hope dis will end the myth of gearbox oil for our Es...

There has been much discussion and debate in the past few years over the use of GL5 Gear Oil in the Sportster Primary/Tranny. This debate centers around warnings that GL5 Gear Oil is corrosive and that it can damage what are known a "yellow" metal parts. Unlike the Big Twins, our Sportsters have a shared primary/tranny and that means that the stator (copper) and clutch spring plate (brass rivets) can be damaged if a corrosive lubricant is used in our application.

The question over the safety of GL5 has been hard to nail down because many of the manufactures will give out conflicting information depending on who you talk to, even within the same company.

WHY is this such a hard question for the oil companies to answer with factual data and WHY is it so hard to find a real answer to the question? The answer is really pretty simple.

Anyone who has spent time studying oil knows about the myriad of various ratings that are applicable for any particular lubricant, from JASO, CF, MIL, etc. The number of different tests that can be done on oil run well into the hundreds, so oil testing by the manufacturer is typically limited to those tests that are applicable to the oils intended use.

So why is it so difficult to get answers to the GL5 corrosive question? It's rather quite simple. Because GL5 is made for use in hypoid gearboxes which by nature don't contain yellow metals, so most manufactures don't perform the standard ASTM D-130 corrosive test on GL5 lubricants.

After quite a bit of digging, it turns out that spAmsoil has actually done ASTM D-130 testing on a number of common/popular GL-5 Gear Oils.

ASTM D-130 ratings fall on a scale going from 1A (least corrosive) to 4C (most corrosive) From a corrosive standpoint, an oil with a 1A or 1B rating is considered safe.

ASTM D-130 ASTM D-4048 FTM-5309 "Detection of Copper Corrosion from Petroleum Products by the Copper Strip Tarnish Test"
A variety of hydrocarbon products including oils, hydraulic fluids, fuel, solvents, etc., can be tested for corrosivity to copper by use of this test. It is limited to products with Ried Vapor pressure no greater than 18 psi (124 kPa). A polished copper strip is immersed in the fluid and heated for a specified time and temperature after which the corrosion is rated by visual comparison to the ASTM Copper Strip Corrosion Standards. The most typical test run is for 24 hours @ 100°C. However, time and temperature can vary according to product type and specification. Results are reported as a number followed by a letter according to the following scheme:

1a slight tarnish a light orange, almost the same as a freshly polished strip
1b dark orange
2a moderate tarnish a claret red
2b lavender
2c multi colored with lavender blue or silver, or both, overlaid on claret red
2d silvery
2e brassy or gold
3a dark tarnish a magenta overcast on brassy strip
3b multi colored with red and green showing (peacock), but no gray
4a corrosion a transparent black, dark gray or brown with peacock green barley showing
4b graphite or lusterless black
4c glossy or jet black

(The ASTM Copper Strip Corrosion Standard is a color reproduction of strips which have the above description.)
