So Bill, what do YOU think of Castrol Edge for a Cushman. As I said, they claim
8 times the lubricity (is that a word?) of Mobil1.
 
If you are in aviation you will recall that poor Mobil1 for airplanes, AV1, got
sued out of existence on urban legends that were all hoaxes. What a horrid witch
hunt.

hate to be blunt, but i don't think you learned to much. never try to be
an expert out of your field. i work with lubrication every day so i have to
stay on top of it. to each his own. every one has to use what makes them
feel best. who cares what is right for the motor. the cushman engine is as low
tech as you can get. it would probably do fine on cooking oil. i have to g
o with the oil engineers and my own experience building all kinds of
motors. and watching wear patterns on various parts. that's my job as a
machinist. i have to work with aircraft tolerance day in and day out with all
grades
of surface finishes. bill

darn carl i hate to disagree with you again on this oil thing. there is
still plenty of zddp in the new oils.you aren't going to hurt the flat
tappets
in a flat head cushman. the spring pressure is next to nothing. the ones
that are having problems are race engines with hp engines with flat
tappets. they run extreme valve spring pressures. there are still alot of
new
cars and motorcycles that have flat tappets. my gold wing has flat tappets
and
it calls for 10w -30 oil. i use mobil1 10w-30 in every thing i own
including the flat head cushmans i had. never had an oil related
problem.the new
oils contain a minimum of 800 ppm of zddp this is only down about 300ppm
from
the old oils.the new slicker moly more than makes up for it. folks need to
catch up with the new hi tech era. these new oils are so superior to the
old crap and it gets better all the time. it won't be long thick oil won't
even be available for automotive use. low viscosity oils just cool and
lubricate better. you got to get out of that old school thinking and enter
the
new hi tech world. old wives tales aren't worth the powder to blow them
up.

Thanks. Good to know others are using multi-grades.

I just put a quart of new Castrol Edge oil in my engine. It claims 8 times
better lubrication than Mobil1 on their ad on the yahoomail page from
which I just clicked away.

The guy who recently worked on my scoot put 30 wt oil in there. I asked
him if it were non-detergent and he said no. I don't recall his entire
comments, but it was like this is just a non-fancy basic oil.

He said that multi-grades and esp. synthetics are not good for Cushmans in
that the oil pump does not do well in getting them up and into the
necessary spots.

I would be interested in what others think about using multi-grades and
synthetics and what they might think about Castrol's claim.
