Using Liqui Moly Gear Box Additive in my Thar CRDe:

Synchro rings have a habit of wearing out in the Thar CRDe, especially if you drive in bumper-to-bumper traffic and have the habit of shifting gears often instead of lugging on a higher gear at half-clutch.
Somewhere around 20,000 km, during my synchro-ring replacement, I got a brainwave of adding a tube of Liqui Moly Gear Box additive to transmission oil. I felt that the gear-box had become ultra-smooth, but it was good while it lasted.

At around 30,000 km, I again had a problem with worn-out synchros. I did not have much time to spare, just had the synchros replaced and used Mobil's trasmission oil.
I had no problems until I reached 85,000 km. When I replaced the synchros, the old Liqui Moly additive bug bit me hard. I used two tubes of additive with Motul Gear Box oil after the gearbox was fully overhauled.

Guess what? After barely 8,000 km the synchos failed again!

I then did a lot of research on the Liqui Moly Gear box additive. It should NEVER be used in gearboxes with brass synchro rings.
Initially, the additive gives the placebo feeling of a very smooth shift, when in fact the molybdenum in the additive doen not allow the synchronizers to function and in fact, causes them to prematurely wear.
Having learnt my lesson the hard (and expensive) way, I had the transmission overhauled once again and replaced all synchronizer rings with their hubs.
Oil used was Mahindra's genuine transmission oil with NO additives. Replaced a couple of parts along as well.

I have been driving around for a while now and the gear-box is buttery smooth. No more experiments with truth!

After reaching 93,000 km now (12.75 years), decided to give the engine a total flush. Replaced the engine oil with AMSOIL 5W40, replaced the diesel filter, air filter element and oil filter and the Jeep is as good as new!
The engine gently purrs. Got to drive some more to really fathom how different it is from the Liqui Moly Molygel 5W40 I had used earlier (replaced after 12,000 km).

^ After many months I was able to drive the CRDe for sometime today - It was recently serviced by India Garage (I did not have a choice this time due to where I am and my health condition).

Anyhow it was delightful to drive, felt like it was brand new albeit needing a handbrake adjustment. They spend sometime sorting out the squeaky suspension bits, replaced one tie rod end in the process, fixed whatever the stereo boy had messed up inside the dashboard etc, so it all feels 'toightt'!

So given my love for the Jeep - Please always use consumables sold by either Mahindra`s own parts store (like we have in JC road in Bangalore) or from the ASC. In our engine oil thread it was discussed sometime in the past that whatever they are selling in the name of Maxi### works best for their vehicles, they are of good quality and cheap. It has been my experience with multiple vehicles so far, all of them runs on normal diesel and only ASC sold consumables.

The Synchros are holding up well despite my daughter trying to drive it like an iMT.

I have sweared by all lubes from M&M and mine is 2014 wih 1.09 lakh kms. No engine issues, no tranny no differential or transfer case issues, even the clutch has never been overhauled. This is near Toyota dependability
My schedule:
I change engine oil with Maximile FEO every year.
I change transmission oil with Maximile Syntec F2 every 2 years along with Maximile Elite in the rear differential.
Brake and clutch fluids are replaced every 2 years with DOT3. Replaced and not topped up.
Recently changed the poly V belt and alternator belt. Lubricate the hubs with power steering oil.
Change fuel filter every 2 years. Transfer case with Maximile GO Synchro oil changed every 4 years.
My Yokohama Geolanders have lasted 74,000kms and will still pull 5000 more. I do 5 tyre rotation every 10,000kms & maintain 32psi.

This had been one of the most dependable vehicles sold in India.
