1st of all welcome the club bro

Regarding ur Q.

I've heard from other forums the using fuel injector cleaner might harm the fuel divider. why don't u just change the injectors it cost abt $30/pc. alternatively u can try FC60 give Eddie a ring @ 92723423.

btw is ur ride 8v or 16v?

For starters, don't use fully synthetic oil. Previous experience with the fully synthetic oils is that they seem to "burn out" at a faster rate than the semi synthetic ones. Semi synthetic blends with no more than 30% synthetic oil is a good compromise. If you're using Shell/Mobil oils the viscosity rating tends to be between 5W-30 & 5W-40.

This list should help you decide on what type of oil to go for :-

Yo Raskie, thats my usual service interval. ;D Unless you whack your car real hard a 5,000km service interval is fine. General consensus is 10,000kms but in truth aggressively driven vehicles need a shorter interval.

Viknesh as Sir Benz has spoken - swap your injectors. Cleaners may or may not perform up to expectation.

okie ... will keep that in mind ...

hi Sir Benz. sorry for the late reply. been bogged down with work. i drive an 8 valve. just had it serviced and the consumption a bit better. but still hovering abt 400km for 58 litres. abt 7km per l. how many injectors would i have to change? and would it improve the fc or are my figures as good as it gets. Any info would be welcome. thanks.

Hello Mr. 124! I think there's still room to improve in your vehicle's fuel efficiency. My W126 (3 litre engine) gets ~7.5 km/l, but it's a much heavier car. My dad's W124 (2.3 litre 8V engine) gets as high as 9 to 10 km/l, albeit with about two-thirds of distance done on highways.

Hey mr w124,

I'm driving 8v as well, when i bought my car a year back, was getting 7.5km/l ( 80% highway).

This are things i done. to improve my FC.

1. New plug wires

2. New Distributer Cap & Rotor

3. New Nozzles ( btw u need 4)

4. KNN filter

5. New Fuel Pump

6. FC60 fuel additive( this stuff will clean out ur entire fuel system)

Now getting abt 9 -10km/l 80% on highway. Hope this helps.

when you use 92, you have to re-tune your CO! than you will get your FC as good as before

i also alt use 95/98 or 97( go in Malaysia la)
