Patman - another quick oil question
I have used it once or twice, however. I suspect it is a dino-based sythetic and not a true synthetic, however... Unfortunatly, I forgot to read the label.
To be safe, stick with something the Patman recommends highly - Royal Purple synthetic...

I haven't heard too much about Havoline 5w40, I'm not even sure if it's a real synthetic or a group 3 petroleum based "pseudo synthetic"
If you can find me the MSDS on it I can find out if it's a real synthetic or not.
Is the number you referred to printed on the label; does a specific series of numbers indicate a dino-based product versus a true synthetic?

In Europe the group 3 based oils are not allowed to be labelled as synthetic, since technically speaking they are not. Over there the group 3 oils are known as blends.

...the data sheet does not say it is a dino-based product or is a synthetic, however. How do you know it is dino-based.
Have you used all of your Royal Purple yet?
I'm on my last interval with Royal Purple in my wife's car, yes. There are only two quarts left of the free oil they sent me.
