Why Fit An Oil Cooler?
There isn't much of a difference between the fortwo engine and the Roadster engine.
Valves made from a better material
Slightly different camshaft
Different turbo compressor and impeller
Heat exchange oil cooler
So why is it that the fortwo engines start dying about 60,000 miles where as the Roadster supasses this?
The better valves do help a lot as they do burn out on the fortwo but a lot of it must be down to the oil cooler.
So, if fitting an oil cooler could potentially make your engine last longer, why would you not fit one?
