Re: Engine Conditioner
How many k's on the motor, is it running OK?
Most of these things are of dubious benefit, or in other words, a waste of money. A quality oil, changed often, is far better for the motor than any "conditioner".
Having said that, I have put some Molybond oil supplement in the old ute, the molybdenum protects the metal during cold starts. The ute is only started/used once a week, if that. In my daily driver, no additves and change the oil every 5,000 k's.
