Engine Oils

Re: Engine Oils

Due to unavoidable circumstances i have to do with 20w40 oil on my 220,i am making sure that i dont ride it too hard or too long to ensure that engine parts are not damaged.
But i am noticing a peculiar problem.The engine braking has considerably dropped with this oil(motul 3000),can engine oil affect the engine braking?

Not sure about engine braking. But there isn't any issues with running 20w40.. I've used a 20w40 oil for about 5K Kms (two oil changes) and not had any issues.

Re: Engine Oils

Quick first impressions of the Rimula R4 -

- Yesterday did an impromptu 600+ ride, most of it through TN summer time heat. Almost 85% of this was on fast 4/6 lane highways, so the engine was running at its peak most of the time.
- The 'feel' of the oil is as good if not better than Motul 5100T/300V. In fact with the limited run, based purely on 'feel' I'd say on the 220 the R4 felt pretty close to the 300v. On super long one day rides most oils tend to start get harsh towards the end of the day and the only oils which have held well in this respect on my bike have been the 5100T/300v.
- Gear shifts are nice and precise, I like the smooth click operation
- This could be psychological, but the vibes seemed to be bit more contained at lower speeds i.e. below 100.


So far so good, 600+ kms in day with 4 lane highways + twisties enough for me to say that I'm sure the bike isn't going to 'breakdown' due to this oil, something which I was initially skeptical about.

Note: I am not advising anyone to shift to HDEO or saying its better than regular motorcycle oils, Just posting my observations as I continue to use it. I am OK with the risks such as clutch failure or engine breakdown, its an 120K kms run bike I think I can take these risks now :P

During engine braking the oil gets heated up and becomes thinner. As vacuum is created during engine braking in the combustion chamber, the vacuum tends to pull the oil into the combustion chamber. As the oil has already become thinner it readily slips thru into the combustion chamber. If ur driving style includes engine braking, then you should use a thicker oil like 15W50

There are no links on the internet which says that HDEOs are better than motorcycle engine oils. there are just forum discussions and user experiences which could be psychological as you urself said.

Contrary to this belief, Rimula R4 has a lower viscosity index than AX7. This is mentioned in Shell's MSDS sheets. This actually means that at higher temperatures AX7 provides better protection than R4.

Theoretically yes, but I have not had oil seeping into the combustion chamber while using AX5. I would have seen at least some amount of smoke from the exhaust in the 5K kms that I used AX5 on my 220.

Alright, then lets see if my engine packs up in the next 5-10K kms.

I am sorry i am asking it late but u said a few days back that u have done a whopping 120k on the 220 right?
Can u list down the engine work u have got done in all this time?
Mine is gonna complete 50k soon and i think it needs a new piston kit for sure.

I think this is more for the 220 thread

Quite frankly I don't remember all the work that has gone on it so far, It would be asking too much but to actually go through my posts on the 220Fi thread to see what all work has been done over time.

That said 50K is way too early for bore piston replacement, I had to change mine at 69K. Which is too early too, but it was because the svc center had botched up the de carb job at 30K. You would need to open it up to see the condition of the piston and bore, maybe if things are not too bad you can replace the piston rings to extend life.

Re: Engine Oils

Any review about Mobil Extra 4T 10W40 oil?

[curve_king]

Re: Engine Oils

Is this the full synth which was Mobil 1 before ?

Re: Engine Oils

Used shell ax7 10w40 for about 2000 kms
on removing i found the oil had become too thin and started to feel rough between 1800 to 2000 kms

Initially it was great engine loved to be revved beyond 5000 rpm

Now Motul 3000 4t 20w40 since 100 kms now
Initial impression
Engine picks up very smoothly
Vibrations lower
Cold start prob a little increased (may be because i dont drive much more than 2 yrs just 7500 kms)

Overall i love the feel of the engine so smooth

P.s i use Honda unicorn about 2 yrs old

Not sure about it.

Re: Engine Oils

No. Mobil Extra 4T is semi synthetic and costs 330 odd. OTOH, Mobil 1 Fully Synth costs 1100 something now.

Re: Engine Oils

Oh because I've tried mobil1 full synth 10W40 & experience was good only for about 1700 kms. After that the Szr I ride was crying out for a thicker oil.
Very smooth for 1500kms.
Actually won't comment too much on feel because I guess engine takes a bit of time to adjust & this was just the first time of full synth for the bike.
Did a wee 160 kms round trip though. Carb was tuned almost perfectly but above 90 with pillion was proving to be too harsh for the bike. And the engine even stopped once on an incline (at low speed though).
Oil wasn't fake I double checked.Guess this is the price of using thinner than recommended oil. But in my defence I could say it was Winter season (& bike was given 1 break during)

Motul 20W40 is better than shell as it is JASO certified. When I say JASO certified that means it actually has a certification number. The certification number for Motul 3000 is M033MOT072
Shell oils on the other hand are not actually JASO certified they just have "exceeds/meets JASO standards" printed on the bottle.
Try using the 10W40 technosynthase by Motul. You will be able to reap the benefits of both 10W30 and 20W40 oils together.

If your average driving speed is in the excess of 70 KMPH, then you should go in for oils made from ester base stocks for added piston protection.

Well i initially wanted to try that only 2 problems i had to face

1.non availability
people widely use motul 30004t yes every shop has stock of that but when u ask for other semi synth like gold 3100 4t they say there is no oil

2. pricing is quite high more over i use my bike sparingly maximum 100km in a week not more so i think that would not be oil for me but ill surely try in future only after trying Gulf pride 4t
