Castrol GTx semi-synthetic 15/40 oil

[Guinney1971]

I was told not to use modern oil in a DeLorean engine, and that boggo standard
20w 50 was the right grade as its more suitable to older engines - Halfords also
do a can of 'Classic Motor Oil' which is the same price but nearly £20 a can last
time I looked.

I bought some Comma brand from our local motor factors for my oil change the
other week, £10.99 for a gallon, and my oil pressure is pretty much spot on now I also used Wynn engine flush (£5.99) before changing the oil too.

I guess we all get told different things, and should go by what keeps our cars
happy and running smoothly. 8)
