What oil are you using? I've run a Seat 1.9tdi for 5 years on Millers with no probs, changed every 12 months. Anyone using it in their Yeti?

I've seen Castrol and Mobil with the 507.00 spec any thoughts on whats best. At the moment mine is QG1 variable service, which can be changed to fixed, any thoughts.

I dont care what brand i use, as long it's 504/507. It may be overkill,(fixed) but i dont think so. Stolen from another thread Smith & Allan do a 504/507 in 5L for £24 delivered.

I would imagine your Yeti will have a DPF (Diesel Particulate Filter), therefore you should use the longlife stuff, to 507.00 spec.

I too use Millers oil in my car, so if you've them before, buy their Longlife stuff.
