Motocycle oil in Jimny? was created by 04JimnyNorwegianGuy
So I have put this oil in my engine. It's Shell Advance 4T AX7 10W-40.

Later I read that bike oil has other additives in it like Zinc and Phosforus. These are not so easily "burnt down" and therefore cause damage to cathalyst and perhaps lamdasonde/O2 sensor. On the other hand these particular additives are very good for lubrication of metal-to-metal. For instance some tickeling engine noise disappeared after putting on this oil.

So now I figure I have very good lubrication for the metal parts in engine but not so good conditions for the catalyst/lamdasonde. Does anyone know how quickly this oil will damage these parts? Or is it maybe a myth that it will cause harm?

It was somewhat expensive oil, so I'm asking this before I maybe will remove this oil. Do you you thonk it will be alright to keep it on the engine......


(Yes I know bike oil is made also for lubricating of gears and clutch. But still it has the same viscosity )

I'd just leave it in....it's not like you're putting it in the petrol!

Yeah get your point. Though the car has approx 200.000 km on the counter, so Im assuming its burning some oil.

Putting car oil in a bike is bad.. It causes the clutch to slip due to the oil additives formulated for a bike..
Below is what Mobil says...
Motorcycle oils and passenger car oils are very similar, with the exception of a couple of areas that are key to motorcycle operation. The first area concerns common sumps, or the use of motor oil, to lubricate and cool the transmission. As you know, in a passenger car the transmission is lubricated by an ATF fluid, which has frictional properties required for transmission operation. In a motorcycle, where the engine oil may lubricate the transmission, an engine oil that does not have the same level of friction modification (for fuel economy) of a typical passenger car engine oil will provide better transmission performance in terms of transmission lock-up and slippage. So motorcycle engine oil does not contain the friction modifiers of a passenger car engine oil. The second area of concern for motorcycle engine oils is that they tend to shear (break down viscosity) more quickly than a typical passenger car. Mobil 1™ motorcycle oils are designed to provide exceptional protection against viscosity loss.
