Maximile FEO is a good semi-synthetic oil, available at M&M dealership

I would also suggest to check/replace the break modulators. I have faced a similar situation where the pressure is lost when the car is kept idle overnight.

Update: They had to replace the entire rear axle assembly. It was found to be faulty. After a couple of weeks of waiting, I emailed the VP of customer service at Mahindra. I got a response in about 10 minutes assuring me that the problem will be rectified as soon as possible and a replacement vehicle will be given to me in the meantime. The next day the replacement vehicle was delivered to me and they took my Scorpio to the service center.

It took them about 10 days to get the rear axle assembly from the factory to Bangalore and my car was finally delivered today. Did a long test drive and looks like the issue is sorted out.

Overall, the experience with India Garage was ok, except for the service advisor who kept misleading me. With Mahindra, it has been great. The regional manager for customer service kept updating me on the status and such.

PS: I met another friend of mine who has also got his Scorpio recently and has been complaining of the same issue of noise from the rear axle at speeds above 80kmph. Wonder if its something to do with a particular batch of axles that were manufactured.

Friends, need your advice. For your reference, my car is a 2006 Crde DX and does not have warranty; has clocked 87000+.

I have been getting my car serviced by either of two FNGs over the last two years amd they have been doing a satisfactory job. One of them is a Castrol service centre with all the tools too. During the last service, the Castrol chap said its time to get my vehicles suspension overhaul done. I took a second opinion from the other FNG and he confirmed the same. Now, my question is- should I go back to the ASC for this job, or is it fine to get the overhaul done by one of the FNGs? I have never been comfortable at the ASC due to various reasons earlier and I am not sure if they will do a good job as I will be going back to them after two years....

Look forward to your advice.

Jammy, I would prefer the FNG anyday!

Hey thanks RB2399 ! 5w40 as against the recommended 15w40! I believe maruti is using 10w40 for its fiat diesel engines. I am apprehensive about trying a different grade as my Scorpio warranty is at stake. It's hard to believe that the equivalent for the 15w40 CH4 is not available in our country!

FEO ! What I get from Koncept is Maxmile Crown with a drain period of 20k Kms ( something I will never wait for ) it does not even say semi synthetic. I will need to check Maxmile FEO as suggested....tks.

Supratim07- the ' bling' noise is from the rubber cushion on the front forks. Fork lift your vehicle, tighten both and your problem should go.

The figures are the viscosity of that grade of oil, at two temperatures - Winter and Summer. Exact temperatures are zero and hundred degrees centigrade. The viscosity in multigrade oils changes less, with temperature, hence the two figures.

As long as the figures are beyond the range it is fine. For example
15W40 means

- Viscosity at low temperate is same as exhibited by oil rated at 15. Any value lower is better, hence 5 is better than 15
- Viscosity at high temperature is same as exhibited by oil rated at 40. Any value higher is better. So a 50 here is better than 40.

in Short a 5W40 is better than 15W40. Similarly 5W50 is even better. Better in the sense that it will maintain correct viscosity over a wide range of temperature (not thin out at high temperature or become extremely thick at low temperatures)

Please note that unless you normally spend your time at cold temperatures, say less than 15 degrees, there is no need for a lubricant exhibiting extended low temperature range.

Hi All,

Today I noticed that when I am releasing the accelerator, the car jerks quite a bit as the RPM starts falling. This is happening in all the gears and I was able to identify it in the 5th gear. This is happening when the rpm is falling around 1500, 2 noticeable jerks and then a smooth falling down again. It is a Mhawk 2009 Oct model done around 20k till date. Got the cross, suspension bushes changed less than 6 months back.

I am planing to take it to service center on Tuesday as Monday is holiday. In the meanwhile, if anyone can help me with any thoughts or atleast a few other checks to identify the issue, it will be of great help.

Thanks in advance.

Could be air filter, fuel filter, high possibility of it being related to the EGR, as 1800 to 1500 is where the turbo comes into action and engine parameters change a lot. Do let us know the diagnosis.

FEO IS tested and recommended for 20000 kms drain interval. Use it along with Maximile Syntec F2 transmission oil and Maximile Elite axle oil - it is expected to give fuel efficiency benefit. Semi-synthetic is a relative term and depends on the additives also.

On saturday went to A.S.S to check the noise from front suspension as adviced. Physical observation revealed 2 things:
1. Plastic cover under the right spring has multiple cracks and its torn off.Not sure why but as per Service Adviser it does happen and it might be the cause of the bing noice.Sterring column and all bush are fine nothing visibly wrong while inspecting. Service Advisor wants a day to remove the whole setup to refit the plastic coupling which i informed would do it in my 3rd free servicing.

2.Another thing that i noticed was as a patch neat diesel tank.Looked like some oil has leaked in and mud got accumulated there as rest of the area was clean.S.A tightened the bolts holding the rubber hose and thats it.
Is there anything to worry?

Looks like spillage. Since the bolts have been tightened, clean the underside where you have the dust and observe it, should be rectified now.

No issues observed after 3 days of run, so looks like for the timebeing its resolved. Thanks

my problem is repeating itself again. The battery is fully charged however the remote (both remotes) are not operating the nippon security system. I put the key in the door and unlocked it. The alarm did not go off. All dashboard lights are working and windows etc work however the car doesnt crank. The immobilizer is ofcourse doing its work because the car was locked by the remote and now is waiting for the unlock codes.

I explained this to India Garage and the @#@$@$# want to tow the car to the garage. When i Called them, they had the courage to send a guy on a bike to "inspect" the issue. He dint even have a damn screw driver with him. This was their emergency (road side assistance) number, by the way. I told him to get lost since the car is safely parked in the apartment.

I called Sireesh auto and for the last 2 days they are saying they will get the obd scanner but they havent turned up yet. I guess there is only one and they are using it at the service center.

This is a 10 lac rupee product. I hope mahindra's stocks crash and they all rot in hell for providing such shoddy service and for not having the ability to identify root cause and effective diagnose/repair a problem.

I pointed out this problem at two service center as i had experienced this before. The damn thing self healed and the jokers at the service center did not even bother checking the wiring on the car security system, which i suspect is the problem.

All they did was to check the car battery voltage and the remote battery voltage. thats it.

Did I say that I wish the worst for mahindra? yes i did. I really wish they all just rot in hell.

Oh boy, I really do sympathise with you for this, I did face a similar issue but somehow managed to remote unlock it after repeated attempts. Used the key manually until the next service after which it was rectified (took 2 visits). The Service Stations are pretty hopeless and I do realise that this is an emotional issue but don't loose your cool and just keep hounding as many people as you can and make their life miserable. Kerp going higher up the ladder, the company itself is pretty helpful.
This is the technical solution thread but if there is a retired elderly at home give him a phone, some numbers and ask him to get busy, posing as you. =p
