Diamond Oil is a distributor and a sponsor for our snocross race series and our team, Woodies Racing. They are the best people to work with. They have a very respectful staff, you are always greeted with a smile and it is always a pleasure to talk to them as they are very helpful. Their delivery truck drivers are always prompt and efficient. We have enjoyed working with this company for a while now, wouldnt change a thing. Lowell is a fantastic ambassador for the company as well. Would highly recommend.

Is it company policy for a placarded tanker truck to tailgate through a construction zone?

They don’t answer the phone.

Exceptional customer service!

Horrible customer service. Very unhelpful, never answer phones.

Jason and Lowell has help up us to keep growing our business.
