My observations are
1) Yezdi/jawa are not comfertable on any 2T oils ( overheat, rattle )
2) new type of multigrades do not get mixed up with petrol properly.
3) as far as the Land Rover is conserned I have observed following
a) I am using No.40 monograde ,with some kind of oil saver kind of dose
b) Multigrades dont work properly (rattle ,noise , overheat )
4) In Yezdi if a 20/50 is used , clutch & gearchange are not comfortable.
So I am using 70% of normal oil + 30% of 90 EP oil, so far it is working
properly,( for about 20,000 km )
Now I am thinking of attachment like oil pump/ external feed for Yezdi engine ( as mixing of 20/50 with petrol is not working properly)
Thanks for reply

Motul and Castrol have SAE 50 oils available in the UK for classic cars/motorcycles. Sourcing the oil from there should be possible but the costs will probably be prohibitive.
IIRC some marine engines also need SAE 50 grade oil - do check with people familiar with those.

@Sudarshan: I am surprised by your statement, but I guess the engine is a 2-stroker. Then a multigrade WILL not work. Yes SAE90 is what your EP oil is, can be mixed with SAE40 to jack up the viscosity.

1) I am mixing the said sae 40 with the sae 90 , for the gearbox of the Yezdi/jawa, ( not for the engine ) . The manufacturer has recomended sae 50 for the gearbox as well as engine !
2) the Yezdi/ jawa I have Are 2 stroke machines, ( Yezdi is 85 production & the Jawa is a 50 production bike )
Thanks for your reply , Sudarshan.

Re: SAE 50 grade oil for Yezdi & Land Rover
this is what we need (I have a jawa twin).
Motul Classic Oil SAE 50 - Oils and Fluids Car Preperation rallying parts for rally cars
Motul Classic Oil SAE 50
Specially formulated all engines of collector cars built before 1950. Suitable for gasoline or Diesel 4 stroke engines. Also suitable for collector bike engines.
PERFORMANCE MOTUL CLASSIC MOTOR OIL is an high performance oil specially designed for old technology engines.
High lubricating power which reduces internal frictions
High film strength available, even in severe conditions
Very low detergency, does not attack seals (TBN : 1.4). Totally inert towards seals used in the past.

Now where in India/Bangalore can we get our hands on this?
