Personally I feel their oil recommendations and technical understanding area is weak, but that is because I have access to information that very few people in the industry do (based on the size of my department and the size of our market share, I would say there are about 300 people in the world who do what I do).
From you, that's probably fair enough, but like you say you are one of the few people in the world that has access to that level of information. When Guy went to your labs he was very impressed with the set up and it's something that we'd never have, but I do feel that compared to other retailers we give pretty good advice.
I think that comes accross in the posts and you don't need to be an expert to see it (though i also used to work in a tribology lab). This is why i always jump at oilman's throat on here.
I'd prefer a straight, buy our oil, here is a discount advert. The theory posts which are wikipedia rehashes purporting to be expert views are annoying.
That said, i still buy my oil from opie oils and will continue to do so. The story of the company is a good one, the customer service excellent and would not hesitate to recommend them. (See Bargy, nice things to say too)
I'm glad you come to us for the oil and that we aren't all bad

I don't go on Wikipedia for data though and in general if people preferred that we just gave you discount codes, that's good with me, it's a lot less work. Just let me know.
Cheers
