[T3] Fw: the story on Oi,?-Message-ID: <"cS9MH.0.gS.Cd1Vt"@maria.yourwebhost.com>





> OK, now I have a minute to write the story on Oil.

> First off.. the heavy oils will increase oil pressure but like trying to
force molasses through a

as well. With an older shot

out of it but other than

a little HP.

> Thin oils, 5W30 etc... these take less energy to pump and is why they are
used on the newer cars.. to

engines are also close tolerance

engine will give you squat

are a good choice.

> Multi Vis.. originally our engines were designed for straight weight oils
as the chemicals used to

air cooled engines run at.
> 10W40 in those days was really more like 15W30 in reality too.  Today
special additives and viscosity

so in order to take advantage

> Here in NY USA where we have hot summers and cold winters the best to use
is 10W30 in the winter and

use 30W in the summer but

> As for synthetics, our engines WERENT made for them.  Some work and
others don't, one that didn't

may be very mistaken and not

full flow filtration as the

this, but only if you ask.. it

filter at all!
