Some people are happy with the superteck oil it appears. We found it unacceptable for our diesel volkswagon engines quite awhile ago. Yet it carries a high rating classification on the label.

It seemed to loose viscosity as far as we could accertain in comparison to all the other base oils we had experience with prior to that. I would never consider using it again.

When decent oils are on sale I usually stock up enough until the next promotional event occurs. Sometimes the local distributors will sell you the oil brands you preffer quietly at the wholesale price. Depends on local policy as they are independantly owned in a lot of cases.

If you buy fuel oil for your furnace talk to them. Sometimes it works well. Oil threads I usually stay away from yet that superteck oil was inferior enough in our applications to get our attention. I personally would not recommend their diesel rated oil to anyone. It is not because I have a particular alternative favorite brand either.

There was and is a major problem also with their in house oil they use when doing oil changes on gas engines. Japanese cars like my son in laws are burning oil now at much lower overall milage than expected. It is the only place he has gotten oil changes done. All at the right scheduled milage interval as recommended by the manufacturer.
