Engine Hesitation
At the start of the year my car was spitting when i put the boot in and took off fast. I got new spark plugs and it fixed the problem. But now the problem has come back. Surley spark plugs last longer than 5 months....

yes they should last a few years unless its burning lots of oil and has fouled up the electrodes ?
More likely a problem with leads this time , or a faulty coilpack. Check the leads for any worn spots where they rub on engine.

I've been using 15w60 semi synth oil, and i've been told that i should be using 20w50? Is that correct.
5 months does seem short even when driving a large amount, the plugs could stuffed/fouled for a variety of reasons bad fuel, wrong heat range, fuel additives or even just fouled from running rich. I would remove the plugs give them a clean and gap them, and see if it fixes the problem.
I would also look at cleaning the AFM.
Replaced everything on a mates 4 cylinder toyota still had a miss rebuilt the carby adjusted everything on it, still had the miss. had dinner and a beer, we went out to check everything again it was getting dark and i saw a new lead shorting out tried 2 of the old ones before we found a good one, problem fixed.
So have a look under the bonnet at night and in the dark you might see a lead shorting out, its hard to see a spark in the day.

15W60 is OK , i've got 20W60 in mine and still OK but not real good for cold weather, too thick at startup. But no, this will not cause your problem.
Try replacing that loose lead, they should be tight at both ends.
