Engine Oils

Re: Engine Oils

Does it have a bad impact on engine ? How to test this engine heat problem ? Any pointers ? I mean if the heat is with in limits or not.

The oil (AX-7) as such will not harm the engine in any way. Though a 10W-30 will flow better than a 10W-40 at the engine's operating temperature and "carry" away the engine heat better - it usually won't be detectable by the rider at good speeds of 50-60 kmph.

The usual complaints of having moved to a heavier oil are slightly higher fuel consumption and slight drop in pick-up. I have, for e.g., used 20W-50 from Valvoline on my GS against the recommended 20W-40 - haven't really felt any excess heat.

An overheating engine will usually run 'rough' - does it still have that Honda smoothness? We will wait on what experienced people have to say about this ( [MENTION=29030]Pinaki[/MENTION] , [MENTION=32286]psr[/MENTION] sir ).

Also, most Honda engines when introduced in India, ran on 20W-40 without problems.

One option is you can settle for a good 10W-30 from Gulf/Valvoline/Veedol/Shell next time if not satisfied reverting back to Honda's oil.

Re: Engine Oils

I hope your mechanic did not alter the carb settings - because a ratio leaning towards the lean side might cause overheating. It is normal to feel some heat especially when driving around in a shorts (which nobody recommends here; but that grocery run) - it is an air cooled engine. Also, it is common to "feel some heat" when crawling at 20-30 kmph for 30 minutes in city traffic than when doing a 60 on the highest gear.

Thanks for the reply ashwanth.r I didn't feel this slight heat issue earlier. Also mechanic didn't touch any carb settings as it was just oil change. I was wearing jeans all the time. My bike Honda Shine 2008 model 125 CC.

I felt slight heat effect on my foot (foot sides only). It's not horrible but I didn't feel this earlier in around 8 years as I was just using showroom Honda mineral oil.

The reason I wanted to go for outside oil is because Honda mineral oil is not providing smooth ride off-late. This Shell AX7 is now giving a better smooth ride except for slight heat to my foot sides. That's what I am worried about.

IMHO, you are just feeling it that way. It is common to experience +/- symptoms after using a new oil. Shell AX-7 have been successfully used in bigger Hondas like Unicorn/CBZ and ZMR/ZMA without any problems of excess heat.

40W oils are way much better for our Indian conditions than a 30W oil - Honda themselves say choose an oil based on the average temperature in your area. An oil should also be chosen carefully based on the Manufacturer. Honda makes some of the best engines with tight tolerances - so 50W is a total overkill.

If you are not really satisfied, you should revert back to 10W-30, but, I still maintain it is not due to the AX-7.

Re: Engine Oils

I have changed my Honda Shine 2008 model engine oil from 10W30 Honda Mineral Oil to 10W40 Shell Semi-Syn AX7. After riding the vehicle for about 700KM, I can feel some heat being radiated to my legs from engine body after a ride of about 5-6 KM in town.

Is this normal ? Does the engine need some time to accustom to 10W40 SS ? Please advice.

Thanks.

Re: Engine Oils

Can I use 15w 50/synthetic engine oil on my Suzuki Access. What will be the effect cons & Pron

The recommended oil is 10W-30 for Access. One can go upto xW-40 for Access as many are using oils like AX-7 with success. 15W-50 would be too thick for the Access' engine and is not recommended.

Re: Engine Oils

I think the DTSi oil is a mixture of Synthetic and Mineral oil.

Re: Engine Oils

can u suggest an oil for my friend's Bajaj Discover 150 ( 2011 Model ). The bike has clocked 23K kms. Shall I use Motul 5100 Semi-Synthetic?. Or should I go with Bajaj's recommended oil ( DTS-i Oil )?. One more question is whether the Bajaj Oil is Mineral/Semi OR Fully Synthetic?

Bajaj oil is mineral

Re: Engine Oils

Because shell ax7 and ultra have lesser draining period when compared to other brands even though they are semi and fully synthetic.for eg shell ax7 will have a good initial impression.but after 2k kms engine will get rough

Re: Engine Oils

Can anyone help me out here, will filling 20w50 be and Over kill for my 2009 gs150r, odo 66000kms,am not sure but I think 20w50 is mineral or is it semi _ synth, my daily travel is in city 40kms, How will 20w50 fair on long travel like 500kms return trip. Or should I just Put Fully synthetic.

I think fully synthetic will be good given your commute and that you are considering long distance travels as well. Also you get these additives that may help in addition to the oil.

Re: Engine Oils

Semi Synthetic is best for low displacement bikes.
Fully Synthetic is mostly for high displacement bikes, like 300/500cc engines, and above.

Why is this , can you explain a bit please .
