Fluid reommendations for Mercedes-Benz chassis codes

W124, W201 and other passenger cars of their era

  • Engine oil: 5W40 or 10W40, MB229.1 or newer

  • Manual gearbox: MB235.10, GL4 75W80 - 75W90 gear oil

  • Automatic trans: MB236.10 ATF

  • Differential: GL5, 75W85 - 80W90 hypoid gear oil or axle oil (strictly without LSD additives, unless your car has an LSD)

  • Power steering

    • Pre 1987: Dexron II ATF

    • Post 1987: At least MB236.1 spec Power Steering Fluid or Central Hydraulic Fluid (strictly not ATF)

  • Brake fluid: DOT4

  • Coolant: MB325.0 spec antifreeze

  • Fuel:

    • Petrol: - Pre-1986: Premium (Specifically E5) - Post 1986: Standard (E10) should be fine, except for CGI engines, engines not fitted with three-way catalyst from the factory and engines with carburettors (Source - ACEA) - Due to general controversy around th effects of E10 gasoline, I recommend always going for E5 Premium

    • Diesel: regular is fine

  • Filters: Mahle, Mann, Bosch

  • Never use additives in your fluids!



For W602 vans/transporters (as per original workshop manual)

  • Engine oil:

    • Petrol: MB 226.5 or 227.5 10W40

    • Diesel: MB 226.0/1/5, 227.0/1/5, 228.0/1/2/3 10W40

    • Barely any of these specs are aimed for by modern oils if at all, MB229.1/3/5 will work in their place

  • Manual gearbox: MB236.2, MB237 spec ATF (weird, Castrol recommends their Transmax Manual 75W85)

  • Automatic trans: MB236.4/6/7, Dexron II ATF

  • Differential: MB235 hypoid gear oil

  • Unassisted steering: MB236.3 PSF

  • Power steering: MB236.2/3, MB237 PSF

  • Brakefluid: DOT4+, MB331.0

  • Coolant

    • Petrol: MB310, MB325.1/2, 

    • Diesel: MB310, MB325.1

  • Grease: MB267 multipurpose grease

  • Fuel:

    • Petrol: - Pre-1986: Premium (Specifically E5) - Post 1986: Standard (E10) should be fine, except for CGI engines, engines not fitted with three-way catalyst from the factory and engines with carburettors (Source - ACEA) - Due to general controversy around th effects of E10 gasoline, I recommend always going for E5 Premium

    • Diesel: regular is fine

  • Filters: Mahle, Mann, Bosch

  • Never use additives in your fluids!



W202, W210 and passenger cars of their era

  • Engine oil: 5W40 or 10W40, MB229.3 spec or newer

  • Manual gearbox: MB235.10, GL4 75W80 - 75W90 gear oil

  • Automatic trans: MB236.10 ATF

  • Differential: GL5, 75W85 - 80W90 hypoid gear oil or axle oil (strictly without LSD additives, unless your car has an LSD)

  • Power steering: MB236.3 spec Power Steering Fluid or Central Hydraulic Fluid

  • Brake fluid: DOT4 or DOT4+, MB331.0

  • Coolant: MB325.0

  • Fuel:

    • Petrol: - Pre-1986: Premium (Specifically E5) - Post 1986: Standard (E10) should be fine, except for CGI engines, engines not fitted with three-way catalyst from the factory and engines with carburettors (Source - ACEA) - Due to general controversy around th effects of E10 gasoline, I recommend always going for E5 Premium

Rectifying OM605/OM606 fuel system leaks

OM605 and OM606 The last Bosch injection diesel engines from Mercedes-Benz… DOHC, prechamber combustion, efficiency, responsiveness, and the well-known kle-kle-kle-kle idle sound. Introduced in the 1990s, the OM605 and OM606 engine pair can be seen as updates to the earlier OM602 and OM603 engines. In keeping with the spirit of the era, they were equipped with several then-modern developments: an EGR valve, a throttle valve (to reduce engine braking), ECU-based engine management and—what will concern us here—EDC (Electronic Diesel Control). The EDC system also brought a new injection pump. In principle it is similar to the earlier units, however throttle input is no longer transmitted via a cable but by a sensor–servo motor pair, and engine shutoff is handled by the same servo motor and an electric shutoff valve instead of the earlier vacuum-operated solution. The old, fully mechanical injection pump - source: Peachparts.com The new EDC injection pump with the shutoff valve instal...

OM605/OM606 üzemanyag rendszer szivárgás-elhárítás

OM605 és OM606 A Mercedes-Benz utolsó Bosch adagolós dízelmotor típusai... DOHC, előkamra, takarékosság, dinamika és a jól ismert kle-kle-kle-kle alapjárat. A 90-es években bemutatott, OM602 és OM603 motorok frissítéseként értelmezhető motor párost a kor szellemében több akkori modern fejlesztéssel láttak el: EGR szelep, fojtószelep (a motorfék gyengítésére), ECU-s motorvezérlés és - ami minket most érdekelni fog - EDC (Electronic Diesel Control, azaz Elektronikus Dízel Vezérlés). Az EDC rendszer egy új adagolót is hozott - elvben ugyanaz, mint a korábbiak, azonban a gázpedál mozgását már nem bowden, hanem egy jeladó-szervomotor páros továbbítja, a leállításért pedig ugyanez a szervomotor, illetve az elektromos leállító szelep felel a korábbi vákuumos megoldás helyett. A régi, teljesen mechanikus adagoló - forrás: Peachparts.com Az új, EDC adagoló, rajta a leállító szeleppel - forrás: Kleinanzeigen.de A leállítószelep Az új adagolóhoz módosított üzemanyagszűrő foglalat és új, teljesen ...
