What oil was in it before?
The grade and brand of oil are irrelevant to the consumption of it, if that's what you're thinking?
Oilman from Opie Oils put up a very informative post recently on oil, I'll try and dig it out for you.
Lol, I had it on my RA, I replaced with another wing the same colour with no rust. Not a perfect match by any means but was pretty close. Personally I wouldn't consider that on a silver car as it's THE worst to match.
Are Clark's still doing servicing Davey?
Regardless of the fire they had last week or the week before, they are still supplying parts but I'm not certain on the servicing. I honestly thought they had stopped it. I hope that's not the case.
