summer oil 60w, 70w ??

[ajlorh]

Any thoughts on running 60w oil in hot summer months (always above 60 degrees). Not as convenient as the good old 20-50w- but seems to make sense in 90+ degree oil

Your thoughts would be appreciated.
Thanks, ajl

I ran 20/60 Redline oil in the High temps in Az.
Really saw NO difference in oil pressure as 20/50 worked just as good..Never ran Hot enough with the oil cooler using 20/50...

The 20/60 was 3$$ more a Quart, so I went back to the 20/50..

Straight 60 is too heavy in my book

I think you will find that the straight 60 wt is a bit too heavy. If you think of the orifice in the piston oilers that are basically used to cool the pistons and running a 60 wt would cut down on the flow from these, it may not be a good idea. Plus the tolerances in the newer motors are a bit tighter than the older engines that used that weight oil.

IMO that is old school for pre evo and twin cam motors, They needed all the help they could get:s I ran Kendall Nitro 70 weight in my 1960 FL
