Thread: Ford ranger 2 litre bi turbo

That you cannot. As far as towing, the more power you can get at low RPM (before the hair dryer can do anything) the better off you are. Otherwise, you're running to the limit of the design and materials spec'd internally and also the clearances for oils. In the old days, it was pretty standard to run basically 25thou clearances and the oils were spec'd to match. Now the clearances are much closer and the the oils much skinnier and relying on the tech and the additives to keep the metal bits apart. And stretching the service intervals right out which is OK in normal service, but as soon as you start towing 100% of the time you're in severe duty and not one of the sealers advises you to close your service times up in this case!
