Yamaha fzs engine over heating

The engine oil specification of TVS Scooty Pep Plus is 20W-40 Motul, Mobil, Shell-helix and Castrol are some of the popular oil manufacturers. change at every 2000 ~ 2500 km

The 2.2 is a great engine I would reward it with castrol 20w 50 in the summer and castrol 10w 40 in the winter

Your machine came from Yamaha with 20w-40 JASO MA motorcycle oil. Use any oil that has the JASO MA rating on the label. 10W-40 for cooler climate and 20W-50 for warmer climates. Do not use any oil that says "Energy Conserving" on the label, they can shorten the life of your wet clutch and transmission gears. Synthetic oils will help your engine run cooler and shift easier. An inexpensive full synthetic oil that is JASO MA rated and available every where is Shell Rotella T 15W-40 synthetic oil (about $23 a gallon).

use genuine hero honda oil as company prescribed or castrol oil.engine oil grade is 20W 40.Amount is 900 ml for cd dawn

Use motorcycle oil. It should have the JASO MA rating on the bottle . Do not use any oil that says Energy Conserving on the label , it will shorten the life of your wet clutch and transmission gears(wrong additives). Use 10w-40 for colder climates and 20w-50 for warm climates/touring. Synthetics will help your bike run cooler and shift easier. Amsoil and Mobile 1 make good motorcycle oil. Yamaha full synthetic (all there oil) is kind of expensive. Suzuki has a 15w-50 full synthetic that is reasonable ($7 a quart last time I got it)

The original manual states :-
Engine oil for XS1100
not below 5 Celsius (40F) SAE 20W/40 SE
not above 15 Celsius (60F) SAE 10W/30 SE

You will be lucky to find SE spec these days though!!

I think you should wait until you know the ambient temp will not go below about 50. If you've ever seen a 20w50 at or near freezing temperatures, it is as thick as honey. This is hard on oil pumps and it take a few second longer for the pump to start building pressure. I think a better choice might be to put in an additive like Lucas or STP. These additives tend to cling to bearings and reduce wear at engine start-up.

Lucas Motor Oil....Definitely worth the money! I have it in my 76 Chevy Stepside Pick Up.

You can use any good oil like SHELL HELIX Super 20w 40.
CASTROL GTX 20W 50.
and change filter at the same time.

Dear Pravin,

Always check for the oil level before you start for the first time during the day. If you can just shake the bike you'll know how thick or light the oil is. The more lighter, you'll have to change faster. Also check for color. Oil can be maroon/red/dark green/etc. depending on brand. If its really black, change it fast. Dont do top ups. Better drain the entire oil and fill fresh oil.

The oil also acts as a lubricant to the gearbox. If you feel gear shifting is becoming too slippery or too tough, check for the viscousity, as said earlier. Slipping gear shift can also be due to a loose chain. So check for that too.

By the time you finish 1500 kms or 2000kms, its better to change the oil.

It is better to use Castrol Power1 for Pulsar. It prevents overheating and also keeps the engine and gearbox smooth. It also maintains viscousity at high temperatures for better lubrication.

My experience:

I used to put servo and every 900-1000 kms i had to change oil. Now with Castrol, I change only between 1500-2000kms. I'm getting mileage between 50 and 55kms for a litre of unleaded petrol.

Hope this helps in solving your problem.

Have a nice time riding pulsar.

Always wear helmet and drive safely.
