Yeah I agree,
IMO - this 15,000 between oil changes is a worry.
Has engine and oil technology improved so much ?
Or is it the outer tolerance of oil change duration, a technical vs cost trade-off or is it to do with competative positioning.
I have been doing the wife's ED XR6 every 5,000 and using Helix Super (the grey container) as well.
I do my own lubs and the money saved by not going to a service place more than pays for the good oils. I do almost all my own repair work and invest the savings in good parts (DBA slotteds, etc).
I will be using the Mobil XHP Plus 15W40 and Ford filters in the new XR8 as it is under warranty and I take no risks. It will get new oil/filter at 7,500km intervals at maximum.
I know Ford engines are the ducks guts, but.....
The XR family ---->
Muzza: a XR8 AU seriesIII...bog standard :)
TBH: (the better half) drives an ED XR6 wagon (Mock Dev 4 160rwkw, JMM extractors, 4 electric windows, Ghia door panels in XR trim, rear head & arm rests in XR trim, Momo s/wheel with Cruise, EL thermos, EBGT wheels, etc) things to come soon = EECV upgrade.
