4JX1 - Isuzu Trooper troubles already resolved?

Hmm... now that's different, to the best of my knowledge, 5W30 is the one that is supposed to be used. I wonder if its because with the replaced injectors it can now use 10W30? Calling on the more experienced 4JX1 owners here!

Thank you

You can check that by looking at the engine number at the identification plate somewhere at the engine bay or the engine # indicated in the Certificate of Registration.

But if that is a locally sold (purchased) ISUZU Trooper, I am almost 100% sure that is a 4JX1 engine. (since I believe 4JX1 engines started since '99/'00 until the Trooper's last production.

..... unless, the precious owner replaced the engine prior to your purchase with a 4JG2.

Thanks Benzmizer! I should be seing "4JX1" in the engine number of the CR? Is that right?

Im still wondering why Isuzu stopped the production of the "Trooper" line and replaced with the Alterra. Is it because of the 4JX1 problem?

Just realized that new models are still coming out for Trooper's counterparts like Prado, Pajero, Patrol..

When you see UBS73- in your chassis or CR.
