Hi Sergey,

it really doesn´t matter what Oil-make you choose...all manufacturers you named make high-quality oil. And as the Bulldog-motor is not too powerful and, more important, not too high-revving it doesn´t need highest-quality motor-oil..

My Bulldog gets an oil-change (with filter!) twice a year with 10W40 part-sythetic oil from Polo and it still runs perfectly after seven years and nearly 50.000 km´s...even the valves have not needed an adjustment yet and even the clutch still works perfectly!!

The situation is a little different for the kardanic transmission in the rear..: The oil in there could still be the low-quality gear-oil filled in at the factory :shock: the result being, that after a fast ride in cold or humid weather, oil can spill out of the venting-dome on top of the casing. The reason is not too much oil..the reason is foam! This does not happen with a high-quality gear-oi from Castrol for example. They have a SAE 80/90 Hypoid-gear-oil GL4, GL5 or GL6...all of them work extremely well..

Any more questions?? ask away.. :wink:

Hi Axman!

thans for advice.

The difference in the price between manufacturers is more than in 2 times...

Usually I use Liqui Moly semisynthetic 10W40 oil. it's not so expensive like Motul. and there are not any motor problems.

Are there any oil tests in magazins?

Hi Strelnikov,

there might be tests but I haven´t read any lately...sorry.

Just make sure, that you use motoroil for motorcycles...then you can be certain that the clutch doesn´t slip.
