Ok I have been checking the site. What I am looking for is any documentation of Synthetic oils being too thin for some cars oil pumps. I have heard this on other sites, But found nothing to back it up. Are people just not educated or what. I think I need some light shed on this. Thank you in advance.

Viscosity of synthetics are no different than other oils. Viscosities are measured in centistokes(cSt). 30 wt oils are around 10 cSt. whether they are syn or non syn.(at 210F). In colder temps a 5 wt. oil is in the neighborhood of 0F is say 1000cSt. whether it is syn or non syn. [Smile]
