Well sorry to hear that your FE has dropped so much. Looks like there is some other issue. The Oil grade used by you is correct? I would suggest double check that once again.

I have a suzuki access, I've changed to shell 10w30 Oil twice, the FE is 44KMPL. I've also tried Castrol 10w30 the FE was 45KMPL. During the first 3 services, Mineral Oil was used by the authorised dealer, FE was about 42KMPL that time, the FE improved post 3 services.
(This Suzuki Access was purchased in the very first month of launch in india)

I Also have a Suzuki Fiero, Again i've used Castrol Power1, Shell 15w40, Castrol 20W50, I've always got FE between 58KMPL to 63KMPL. The Bike has crossed 60000km now.

Hope this helps! Cheers

Even i moved to 'Total Quartz 5000 15W40' in my Alto's last service. Did feel an improvement over the earlier 'Shell MGO'. But to be fair one would feel improvement automatically, from changing a 10k run oil to new oil.

No one will use car engine oil to two wheeler. I am talking about the shell 20w-40 4T Motorcycle oil only.

What is the oil grade recommended in your manual? Where was the oil change done? Is there any gasket/seal/washer replacement required with every oil change, which they failed to do perhaps? Did they clean the oil filter? Finally, is there an overfill?

You may have overfilled the oil beyond the specified quantity.So only dropin FE and leakage of oil.

Drain all the oil into a measuring jar and put back the quantity specified in the manual

A better way is to use the dipstick to measure. Because the quantity varies with and without oil filter.

Fill the oil till the level is middle of the dipstick. Start the engine for 10 secs, switch off, and refill it, till the level. Make sure engine is cold.

Re: ARTICLE: Synthetic oil vs Mineral oil

I drive a 2002 Ohc vtec.It has done 105k.I bought it when it had done 100k.I have installed a few things after i have bought it and tht include an Intake manifold,AEM intake,FFE,upgraded my wheels to 16inchers.I am thinking of going for a complete service.I was worried from the start about the fuel economy figures.The check engine light never goes off.Earlier i thought it may be due to the O2sensor or cat converter or choked exhaust but now everything has been replaced but still the fuel economy figures worries me a lot.I am gettin an average of 6-7.
As part of maintenance, I am thinking of getting a complete major service done that includes:

- Mobil 1 5W-50 engine oil change + filter
- Brake line bleeding and fluid change.
- Brakes checked & cleaned
- Radiator flush & engine coolant change
- Power steering oil flush & refill
- Fuel filter changed
- Transmission oil flush & change

As i am going for a major service i was thinking of shifting frm mineral to mobil1 synthetic.I wanted to take every1's opinion before going for the service as in what u ppl have to say.Any suggestion is welcomed.

Well, I know many who have tried and were all greeted with oil leaks

Re: ARTICLE: Synthetic oil vs Mineral oil

Hello all,

Im sorry for going off topic but i already made a post here:
http://www.team-bhp.com/forum/long-t...ml#post2406277

Since i did not get a reply there, i am posting same query here as more people familiar with engine oils view this thread.

Can anyone tell me what grade mineral oil is used in NHC. I believe they use Idemitsu which is made by Savita Chemicals in India. But i dont know the SAE viscosity, I think it will help lots of people as like me many are fed up of Honda Dealers.
my NHC has run 50k KM on normal mineral oil from Honda A.S.S. I want to keep using mineral or semi-synth so the grading of mineral oil poured into NHC would be very useful.

Also looking at this pdf:
http://www.savita.com/pdf/idemitsu.pdf

It just shows one HONDA Genuine Oil which is 20W50 SJ! What is the correct oil spec?

I am sure3 you forgot that wait for 10 minutes after switching off before checking and topping up.

Re: Hawk-On-Fours® (H-4®) with a tail - Scorpio mHawk 4WD

I inspected the Mahindra Maxi Mile 6 litre plastic jar (HDPE ) today. It is 100 % mineral oil made by IOL - Indian Oil Corporation, Servo, 15 W 40.

This is the engine oil being poured in service at the dealerships in Scorpio, 4x4 scorpio and Xylo.

The lable says its good for 20,000 KM - IT IS NOT good for 20,000 K - the maximum maximum limit is 10,000 KM and best is 6,000 KM.

If this is your oil from day 1 never switch to semi synthetic or fully synthetic engine oil - it will damage the engine. Mineral oil bloats the rubber seals in the engine and the engine becomes capable of running on mineral oil viscocity only. Use of synthetic oil which is less viscous will cause leaks in the seals resulting in engine damage.

I am telling you this from experience, a lot of Arab lads damaged their Nissan Patrols by chsnging from mineral oil ( Caltex or Eppco 20W50 or 15W40 ) to Mobile 1 and BP Visco 5000

Re: Hawk-On-Fours® (H-4®) with a tail - Scorpio mHawk 4WD

If what you are writing is true, then many of us who have moved to Synthetic (or semi-synthetic) oil from mineral oil should suffer this issue. For example, I have shifted from the Mineral oil used in TASC (Mobil, they tell me) to Selenia (which I believe is semi-synthetic, while the pack claims it is synthetic) after 70,000 km. So even I am likely to damage the oil seals?

Re: Hawk-On-Fours® (H-4®) with a tail - Scorpio mHawk 4WD

It has happened in a lot of Nissan Patrols with 4800 cc I6 petrol engines, also in Landcruisers with the I6 4500 cc 1FZVE engines, how can I say what will happen to other car engines, only time will tell.

In mineral oil the oil seals made of rubber bloat, they contract when synthetic oil is used and create a gap. This starts the problems therefore it is recommended to use only one type of oil from day one API-SJ or higher grade suitable to temperature ranges in your country, both 15W40 or 20W50 meet the grade for India. A rare to find 15W45 meets the grade perfectly, the engine has less pumping to do with the same heat rating specifications of 20W50 when every bhp matters in very tough dune climbs on loose powdery sand all this comes into play but not really in Indian off road conditions or highway driving.

Well, while I understand the reasoning behind your statement, on a personal note, I hope it doesn't turn out true for me. However, now there's no looking back. I have moved to Selenia from mineral at 70,000 km and I also understand that moving back to mineral oil is not really advisable. So there it stands.

Re: Hawk-On-Fours® (H-4®) with a tail - Scorpio mHawk 4WD

What I said above has been from experience with extremely seasoned and Toyota - Japan trained specialist technicians from Al Futtaim Motors - Toyota, AFM Service Managers of at least 3 workshops in Dubai, Sharjah and Abu Dhabi, experience of my swiss friend David Lees - (the Yeti )an avid offroader, my GPS techniques teacher who is techical head CATERPILLAR Middle East, while the weekends are off road in his two SWB 2 Door Nissan Patrols the other driven by his swiss wife Bridgette Lees, Dave on weekdays attends to huge Caterpillar gensets in backwaters of Afghanistan, Yemen and god alone knows where, so he should know what he is saying. He is also a mountain climber and at age 56 he puts me to shame - Dave can lift a wheel of Nissan Patrol and replace it single handidly, its a 265/70/R16 tyre with 7x16jj alloy wheels! A guy whom I would always like to be off road with me.
