Careful sending when being checked theyre charging you for upgraded oil n filter if it doesnt fail..

It stated on my recall letter that they will replace oil & filter foc if required. When they had mine for recall recently oil & filter were not changed because car had been serviced by them in Feb & obviously the current spec oil Total Ineo RCP 5w30 was used then. Provided there is the previous 3 years of service history available then they will replace top end or entire engine as required within the period 10 years or 150k miles.
