Looking for advice on best oils for SP250.
Original spec was Sae 30 for both.
Many seem to have gone with Castrol XL20/50 for engine and Xxl30 for g/b (or Penrite GB30)
There is the Halfords Classic range which is value for money and suitable as is the Morris Oils range of 20/50s where you can bulk buy. or indeed the Castrol Classic range
Engine and gearbox use the same grade and the rear axle EP70/90
