Sa Aussie I read that their problem is diesel fuel getting into the engine oil. Exactly how this happens I dunno

From experience, you'll may have problems when it reaches 70-75k km due to injector sleeve o-rings. Just have them replaced before it reaches this mileage.

Yes, it is casa-maintained. Thank you, I will remember your tip.

I sold my trooper 4jx1 91 model 950k. Very well maintained. kakainis mas me alam pa ako ke sa mga mekaniko sa casa. if you can get it at 800k ok na.

jack: Can we conclude then that if you use Besco all the way and have the o-ring sleeve replaced say every 70k km that the 4JX1 motor is still a good buy? Nga pala ilan km/liter average ng 4JX1? Thanks!

Besco motor oil is the same as other brand of motor oil. oil recomended for 4jx1 10-30 or 5-30w. one 5-30w brand is Havoline Energy. Good product but i dont know if suitable for philippine temperature.

My engine used Petron all terrain 5w30 oil, replaced the injectors, rpcv and injector sleeve orings at 70k km based on tec 2 diagnosis. I have seen 2 other engines develop problems caused by failing injector sleeve orings (when orings fail, the fuel and oil will mix) at around 70-75k km.
Sold my trooper to a friend who has not had any problems and does 8-9 km/L regularly. He had the EGR disconnected so no more smoke issues.
At second hand trooper prices, the injector sleeves, injectors, rpcv repair cost is worth it at least for the next 70k km.
