My Plus8 with Gems management ran better on V-Power higher octane. The management light came on occasionally using std 95 octane. Checked everything but no joy. Started using the V-Power and it stopped.
The Plus Four runs on either E5 or E10. No really obvious difference in performance but slightly better mpg with E10. As happened too with the Plus8.
The Plus Four just had it's first annual service on Friday with 7k miles done. Two extras sorted. Loose grill and rear clunk at low speed stop-start.The graphite grease spline lube looks to have worked. Long winded crawl home on the M4 with a lot of stop-start and no clunk.
