I used to manage a fleet comprised of vans and cars.......


I would never in my life use Shell engine oils or waste my money on Mobil 1. during testing phase for the vans during the mid 90s , I bought the oil from a Shell petrol station myself. The van did not run well at all. I switched it out for 'other' brands until settling on Castrol.

For my money Castrol Edge 10w-60, this is used in the salesman car. All fluids changed once a year, compared to another unit which is self managed (not me) religiously on Mobil 1 0W-XX. The one on the Castrol is still running strong at 2XX,XX km (need to look at the odometer again) and the one on the mobil is currently awaiting top end overhaul work at 1XX,XX km (again need to look at the odometer to confirm).

yes you can call me a Castrol man, I dont see myself using anything else. but I stay away from the magnatec series because I prefer extended service intervals.
