Re: Synthetic vs Organic
Mobil currently offers the following fully synthetic oils (at least in
Mobil 1 0W40 - VW 500.00/505.00 approval
Mobil 1 5W50 - VW 501.01/505.00 approval
Mobil 1 5W40 - VW 500.00/505.00 approval
Prices for the three (list) here are USD 14.00/12.00/12.00 per litre
(approximately) here. Ouch!
The VW 500.00 approved oils are more expensive, but for our climate they
offer the best year-round protection, good cold-starting capabilities, and
low frictional losses. One must remember that if using VW 500.00 approved
oil on Turbodiesels, the oil should also have the VW 505.00 (more
traditional multi-grade) approval.
This is a can of worms, I don't want to open it much further, but we use
only Mobil 1 0W40 on our demos/company cars. Most of customers seem to
agree. We do not sell the any oils that do not have the VW approval
required for the particular application. Find an oil with the VW
500.00/505.00 approval and you should be safe.
