Need some engine oil advice

Recommended Posts

OK,  I've got a cb500x honda motorbike that is about due for an oil change.   Back home we run rotella t6 Synthetic 15w40 diesel oil.  Works well in a wet clutch and is about $25 per gallon.

It appears that they do not offer t6 rotella in the s.e. asian theater.

 

Apparently,  the Shell Company offers Rimula Synthetic diesel oil here, and I am trying to find the closest match to the Rotella.

 

I am not going to cough up   690U for a liter of Motul 4t 7100 Synthetic..  Actually 3 liters.

 

What are you guys running?

I think you will find that Rimula is Rotella. Try finding Rimula in the US. T6 is probably the same as Rimula R6

 

New problem is finding Rimula R6.

I was always told that in hot climates the oil needs to be thicker..... so say 5w40 is not the ideal and to go for a higher "W rate like say 10W40 or 15w40 ... but then I am no grease monkey so don't take it for granted !

Thanks all,  and especially jackdd.   I do my own wrenching even though I could have a shop do it.   I am really particular about my bike.

I also use Elf ( Total ) Moto 4 Tech 10/50 Fully Synthetic , from the Honda shop , near the bus station in Chiang Mai. The first viscosity number ( 10 or 15 ) isnt really important here. Your engine oil will rarely be below 15 degrees Celsius. I believe Shell Rimula is a "EF" energy efficient / "EC" energy conservation oil. Rotella was not. So it could effect wet clutches. Rotella t6  is a 5/40.

can't really speak for motor cycle engines but as a long time engineer and self repair car guy, I am totally sold on 100 per cent synthetic oils in car engines.  I have never seen engine oil changes come out so clean and the cars seem to love it.  I use valvoline.  My friend swears on Mobil.  Yes it is more expensive than tradition dinosaur oil, but since I have kept each of my last two cars to over 250K miles, to me, the cost is worth it.  I have never needed any sort of engine job.  My current car is a 2008 Kia Sorrento SUV with 85k miles on it.  Runs great.  All my cars have been in the USA winters, deserts, humid Florida, places.

on a non hi performance engine like the cb500x, the Motul 5100 semi is fine. In fact fully synthetic oils are not needed in road going vehicles at all. Unless you are running your vehicle at track days with your engine at sustained high RPM regularly, you are just throwing money away.

 

If you are anal about your engine other than what the manufacturer suggests, why not just just drop the oil change intervals and make sure you always change filters at oil change.

 

If you want to read more about modern oils, read up on "polymer shear" of engine oils. Sometimes Fully synthetic can be a worse way to go for road based vehicles.

I suppose I could roll my own semisynth out of 2 bottles of semi and one of 100% synth.   It'd be cheaper,  and nearly as good as full synth.

Motul is just way over priced. They have to get the money back which they spend on all the advertising

You understood something wrong

So here in Thailand it's completely irrelevant if it's 10w-50, 15w-50 or 20w-50, because it won't be below -20 degrees celsius.

But as mentioned before, sometimes it's above 40 degrees celsius, so using an engine oil which is good up to 50 degrees makes sense

The OP referred to Motul 7100. That is why I suggested 5100. Of course and major semi synthetic will be suitable.  But I wasn't aware the Motul have a larger advertising budget than say, Shell, Mobil, Repsol, Fuchs or other international brand.

 

The point of my post was not about a specific brand, it was that full synthetic oils are simply not needed for the majority of users. There may be some exotic road going vehicles that has a manufacturer recommendation for fully synthetic, but they would be rare.

I looked at the manual for my bike,  and it calls for 10w30, but because I am such a badass and want to buck the system,  I got the 20w50 synth amsoil with the filter thrown in.

 

https://www.lazada.co.th/products/amsoil-20w50-4t-100-946-ml-3-free-oil-filter-oyabun-i345444304-s673978992.html?spm=a2o4m.searchlist.list.9.31806473Ie45Q3&search=1

 

Of course,  I'll need a list of your names and numbers,  so that when my bike bursts into flames and shards of molten engine parts rain down on a distant thai countryside,  I'll have somebody to call and a place to crash until I pick up the mess.

 

Amsoil is made in the USA, and I was too.
