E38 Interior

[ssmann]

How come you don't have the OBC bro? You should be able to see you RANGE on the instrument cluster by cycling the clicks on the stalk.

Bro - mine is a 96 model. I have tried it before but no OBC display.......only check control function......

Bro,
You are getting 800km for full tank (which is 80ltr for E38). I presume its town driving, Thats amazing man.

Ya bro... that's some crazy mileage there bro... I'm getting only 500km on a full tank. Even 680km is damn good... either my engine is not working well or your odometer is not working well.... hahahah!!

This thing must investigate coz fuel cost is killing me... what about other E38 owners? what r u guys getting?

Hmmm....500 on a full tank? Well I pump only Petronas or Shell RON95 and a full tank costs me about RM150. I am pretty sure the odo is working well, and I drive her quite hard at times with a fair bit of city/highway miles. Yesterday, I had 1/2 tank left and the odo was showing 430km....

My E34 on the other hand is a guzzler...I can't even get 300km on a full tank!!!! But that's probably because its always red lining, cause its fun to do!!!!

Yes, would be good to learn what other members are getting from their rides.

Bro YazMeen, sorry to curi your thread like this la....one teh tarik on the house

Yazemeen,

Please state your price for your items. This is part of the forum requirements. Else some action will be taken on your posting.

Thanks.

Done already. Tq for reminding

Mine oso same, no OBC...well, anyone tried to install the OBC from the half cut? or maybe i should start another thread..hehe

and mine i can get only 550-650km for a full tank, with mixed driving, with v-power ron97 summore. so it'll be such a waste for me as u only use ron95..hehe

Bro ssmann, u can always curi my thread la, no problem at all :top:

I only use BHP RON97 (primarily) or Shell 97/vpower97 (if can't get BHP) for my cars... wah, RON 95 can give so good mileage ah.... lemme try next tank.....

But is RON95 good for the engine? Tho the owner's manual say can use, but I'm quite skeptical on the quality of our fuel. On the rotary, RON95 makes the engine absolutely gutless....

Sorry bro Yazmeen... thread kena hijack. BTW, I'll need to pay u a visit soon... gotta get my headlights refurbished.... call u soon to arrange :top:

 

[YaZmEeN]

No problem la fren...just come over when u're free

but i agreed with u about the ron95, afraid it might damage the engine sensors....

Bros - let me tell you a secret.....this is direct from the Chief of Petroleum for a large oil company, and the best version I have seen is on Paultan.com

RON = Reseacrh Octane Number

RON stands for Research Octane Number, a rating used to measure a fuels knocking resistance in spark-ignition internal combustion engines. Knocking is what happens when parts or all of the air-fuel mixture prematurely ignites before the flame from the spark plug can reach it. This can be caused by ignition timing that is too early or engine overheating, where the heat from the cylinder itself causes the mixture to combust before the spark plug can burn the mixture. This causes a decrease in performance and might also harm the engine. It is a misunderstanding to think that RON97 fuels produce more power than RON92 fuels, even more so with the fact that in reality a higher RON number means the fuel burns less easily! RON refers to the ability of the fuel to resist knocking and nothing else. By pumping the RON97 into a car which engine only requires the RON92, all you’re going to get is an emptier wallet – that hardly counts for performance gains via weight reduction!

In summary, most Japanese (I don't have enough insight into RX8 or rotaries, but suspect it is because it is designed for high knocking, thus need a 97 to run. In Japan got RON100 also) and European made models up to year 2006/7 would state that a min RON90 is required to run the engine. But pls ensure it is unleaded :wink:

I promise you, that higher RON does nothing for your engine, mileage or performance, but lower than recommended RON, does.

Hope this helps to clear the myth, from a purely technical petroleum chemistry standpoint :wink:

Bro - try not to use BHP bro. They get their fuel from Spore Refining Company, no longer from BP. My order for ranking on fuel technology additives available to the mass consumer in Msia is as follows (and yes, fuel additives can help in mileage, performance and engine care): -

1. Petronas
2. Shell
3. Caltex
4. Esso/Mobil
5. BHP

 

[suraeisan @ BimmerE38]

Hey guys, Serjit is getting solid millage man. I use only Petronas Ron95 and also get about 500-550km town driving and 700km outstation.

Would really like to hear from others on this subject matter. Will start a new thread to capture the data

R u serious? A lot of RX8er uses either BHP or Vpower as they give the best throttle response (base on driver feedback). For my 8, runs like a dream on BHP97. Since when they swap to SRC instead of BP?? On 95, you might as well drive a kancil... engine damn "heavy" and gutless. BTW, Mazda rec Japan premium fuel (i.e. Ron100) for best performance.

I'll try to swap to 95 on my next fillup on the 7. Will track mileage.... but I'm still worried about what it'll do to the engine.... not so much for more power but the "knocking" bit....

Absolutely bro. Vpower Racing yes, additives are great and thus cost a premium. Otherwise the standard of fuel on the regular 95/97 is comparable, but for the raw crude that is used to produce such products. BHP sources their crude from SRC, post the handover from BP.

All my cars have only been fed 95 and I have no engine issues todate related to poor fuel, etc. Off course one very reputable mechanic (used by tonnes of forumers) once told me that if I use other than 97 on the E38, I will lose power, effect compression and destroy O2 sensor on the engine, and this is an engine that was desinged in the year 1994 onwards......You know what, I never ever visited him ever again, cause this is a load of BS. I wonder what happened to cars pre Ron97 days in Msia then, which I recall was only introduced around year 2002/3 onwards, starting with Vpower Racing???? In addition, Msia has one of the highest RON's around.....most European and Western countries only run 95, with very few offering 97 and above at a very high premium.....

i agree totally with ssman... to be honest guys, all your cars are mean to run on 91. and can run on minimum 89. Basically a goodgrade of kerosene also can sapu. in the states and middle east...mainly 92. 95 is considered premium.

If you can actually feel the different between 95 and 97 on your car.. i assume the smallest here is a 2.8 litre.. you must be a test driver or something. ona 97, it evaporate faster so theoritically should advance your burnt out/timing hence more power. lower Ron, slower,causes knocks and your ecu will retard, hence less power.. significant in small compact engine, but on your 7s, i cannot see that is any different.

If you can actually feelthedifferent,something is not right with ur engine in the first place.. you are not runningthe full potential of it.. having much unburnt fuel due to low VE. might be time to do a head clean up..

The ranking of Petrol Retailer in terms of fuel quality, i am not too sure to agree with ssman . In the pass,it is very true as there is a avery big gapin pricein terms of kerosene and gasolin. Some celaka dealers mix the kerosene into the gasolin they are selling. Petronas had nosuch probleminthose days as all stations, kerajaan punye..company owned. Otherslike shell are mostly Dealer Owned.

Today it is very different. No more kerosene or diesel to mix. Fuel injected carsare so sensitive that it will stop if any foreign fluid is detected. The Veeder-Root sensors are online 24/7 link to every oil majorcontrol room. any changes in density, dew point and level triggeres the alarm. So no change of foul play there.

so..i wont waste my time with higher RONs as it will not make any different to me except RM8 per full tank.

Bro - well said and a detailed technical analysis with practical application. You know a fair bit about the kiosk/supply business :top: My take on petrol brands ranking is based on my knowledge on additive technology allowed in Msia and the ability of respective refineries to produce such technology at optimum cost. But the point here is made, burn money only on higher RON

Noted. Very sorry YazMeen...

haha...i thought this is another thread when reading the replies, until Mr Vincent reminded us...hehe

this is for knowledge and i dun mind at all k...
