Mineral oils with lower NOACK than some synthetics .

Big calcium as well compared to most of the other OTC's today .

I'd like to know if the Sinclair is carrying the big boron like the Motorcraft oil .

They also have a full PAO 5w-40 diesel oil thats built to the hilt in terms of add pack . Relatively light as well coming in around 85 cSt's at 40c . Good price of right at 5.00 per quart but it's hard to find .

Anyone here using Sinclair oils ? I have an analysis to post later . Their 10w-30 synthetic in severe use . Mercury Montego twin cam V-6 . A very well built engine oil for sure .

 

It's good to see the Sinclair name again. There used to be Sinclair stations around these parts, but I havn't seen one in a very long time. Figured they got sold and the name was lost in history. They used to give out little dinosaur toys with every fill up!

Thanks for posting the link and the trip back down memory lane! Their product sounds good. Please share your analysis when it's ready!
