How long does engine oil keep?

[The Edge]

Whats the diffeance between normal edge and the turbodiesel edge? Is it just meeting some other VW standard? Is this relevant to my engine? thanks

Do Costco sell it?

I get My fully-synth Mobil 1 from there at 19.99+vat per 4litres.

Frequently asked question on Castrol's website may help: -

My BMW needs Longlife 04 specification and I see this on EDGE Turbo Diesel 0W-30 – The name says “Turbo Diesel” - can this be used in petrol engines
A. If you have a requirement for BMW Longlife 04 specification in a petrol engined car, you can happily use any of the EDGE products that meet BMW LL04 - ie EDGE Turbo Diesel 0W-30, EDGE 5W-30, EDGE Sport 0W-40 or EDGE Turbo Diesel 5W-40.

With regard to the EDGE Turbo Diesel 0W-30, you can use this in a petrol engine – as this meets the Longlife 04 specification which covers petrol and diesel engines.

I use the Castrol Edge Turbo Diesel 5W-40 in my S2000. Both Honda and Castrol recommend it. After speaking to Castrol they said the "Turbo Diesel" was something their marketing department came up. It is actually suited for petrol and diesel engines.

I have heard lots of good stuff about the TD Edge and it will be the oil I supply on the next service also.

Do you have a costco near you?

I use Mobil1 from there, it's 0w40. About £22 for 4l inc VAT.

Edit- Just read all posts, seems like a good choice Costco. Annual membership is around £30 I think.
