10 000 miles just had 2 opening rockers replaced.
Shell Advance or Rock Oil synthasis 15W50 used max every 3 000 miles, always careful with startup since I bought it 2 years ago at 6 000 miles.
Baines reckon there is a lot of varience in rocker quality depending on the supplier.
Has anyone tried extralube ZX1 or a simular 'friction reducer' addative? |
