There's no question about it. Use synthetic ( or even semi-synthetic ). It's perfectly compatible with traces of the old mineral oil btw - don't fret. At that mileage it would probably pay to run a flushing oil through it too or use a flushing additive when draining the old oil if it's still fairly clean. Graham
