I have a 1998 Jimny that yesterday passed its MOT with advisorys only. Good news BUT, one of the advisorys relate to blue smoke from exhaust on acceleration. I was aware she was losing a bit of oil but not into the engine. What should I do? Are there any products I could add to the engine oil to prolong engine life. Thank you in anticipation.

blue smoke on acceleration is usally piston rings, smoke when you let off is usually valve stem seals.

I wouldnt recommend putting anything into the engine, those miracle cure products usually do more harm than good.

Id nurse it along or look at a second hand engine replacemnt would probably be the cheapest option if it gets really bad.

Blue smoke on start up id say valve stem seals

Blue smoke on deacceleration is piston rings

Blue smoke on acceleration could be blocked breather on the engine or piston ring

I rebulit my engine due to this and put new piston rings and new valve guides and seals in and all sorted
