The 3.2-liter Mitsubishi 4M41 diesel engine has been produced by the concern since 1999 and is installed on popular Pajero SUVs, including the Sport version. At first, the motor was equipped with a distribution pump and only since 2006 with Common Rail.
4M41 is a turbocharged engine with an installed MHI air blower. Compared to its predecessor 4M40, the power has been increased to 165 hp, the torque is 351 Nm and the environmental performance has been improved.
Since 2006, the production of a modernized Common Rail engine began. The turbine changed to IHI variable geometry. The intake ports have been improved, a new intake manifold with swirl phases has been installed and the EGR system has been improved. This made it possible to increase the ecological class, raise the power to 175 hp and a torque of up to 382 Nm.
After another 4 years, the engine was again modified. Power increased to 200 hp, torque – to 441 Nm.
The engine was installed on:
- Mitsubishi Pajero 3 (V70) in 1999 – 2006;
- Mitsubishi Pajero 4 (V90) since 2006;
- Mitsubishi Pajero Sport 2 (KH) in 2008 – 2016;
- Mitsubishi L200 4 (KB) in 2005 – 2014.

Disadvantages of the Mitsubishi 4M41 engine
- In the first versions of the engine without Common Rail, the high pressure fuel pump often failed and the pistons burned out;
- The updated modification has become much more reliable and practically does not bother;
- A crankshaft pulley with a rubber clutch can fall apart even at low mileage;
- The timing chain serves approximately 200 – 250 thousand km, and then it stretches and rings loudly;
- About once every 50,000 km you have to clean the EGR and tighten the alternator belt.
I have a 2014 Pajero with 4m41, what’s the best fuel tonuse as where I live we still have 2 diesel fuels avaliable at the pump, ulsd and plain old school diesel
All the 4M41 versions with a distribution pump (equipping the 3rd generation Pajero) are generating 373Nm or more depending on the destination country. Evenmore, for this same version of 4M41 with a distribution pump there are different level of engine outputs: 160HP, 165HP and 175HP.
Fof example the 4M41 with a distribution pump installed on the 3rd Gen Pajero Japenese specs (JDM) is producing 382Nm and 175HP.
I’ve driven over 470.000km with my timing chain, no noise and no stretch.
The 2 things you need to do is changing oil as required, and change the timing chain guide between the camshafts around 200.000-250.000km.
The chain guide you change at the same time you do the valve clearence check, it’s 2 bolts from the top and takes less than 1min to change.
What’s the difference between the 4m51 caf7238 and the 4m41ha7788 ?

What is the best oil engine for 2011 model mistibishi 3.2ltr diesel engine
Online recommend 5W-30 NGN Nord, 5W-30 Shell HX7, Valvoline Maxlife C3 5W-30. There are also recommendations for 5W-30 Total Rubia 9900 oil, but it is for trucks and does not have the required approvals.
