A friend told me it was quicker to drive from york to london,due to some weird scientific theory. It had something to do with the fact that york is further north, so driving south was easier and quicker due to less of a gravitational pull. Is there any truth to this?

Does your friend also have a bridge to sell you? Variation of earth's gravitational field by latitude is extremely small. Further, the force is perpendicular to your motion, unless one city is at a higher elevation. Still, it isn't easier to drive downhill than uphill. But tell us the theory and we'll try to check it out.

If you use the prescribed routes given by www.theaa.com from Trafalgar Square (being central London) to York and vice versa, it would actually take you 0.4 miles longer in distance and 1 minute longer in time to come back from York than it would to go there.

217 mi ( 349 km) (about 5 hours 3 mins)
Although your friend may be right in theoretical terms, in reality there are more important factors in the time to drive then gravity, like wind, traffic, driving conditions etc.

Practically, no. There are so many other factors which could dominate.
However, there might be some truth to it if you kept the engine at a constant idle theoretically

I think you're confusing gravity and magnetism
