I now have 3 cars to look after -- mine, the wife's, and now no 1 offspring.!
So - oil changes every 6 months can get expensive when using the retail packs - especiall for GTX Maganatec!
Anyone know where, in the Birmingham (UK!) area, I can get magnatec oil in larger quantities at a discount? - I'm sure you used to be able to get 5 gallon drums or somesuch at on time ...
