What weight Oil?

[jeffjeney]

This is specifically for people from Areas like Tucson Az. Do you run 20W50 or 20W60 motor oil? Moving there next spring and want to know what to put in at end of year here. Going to go with Redline. Just wondering if heavier weight is better during super hot months.

Although im not from Az my tech told me that straight 50 wt wont hurt them at all so that is what i run in my 17 ( Lucas),my buddy has a 2015 softail slim with a 110 in it and he runs two quarts of straight 50 and one quart of straight 70 Lucas in his with out any issues.

On the off chance that even works....what would be the advantage to 56.66 wt. to 50 wt. Oil?

OOOPS I dunno about oil Threads and choices

All I know is what works 4 one WELLLL

Oil is like a religion to some

If it works I guess let it be

I never used Synthetic oil in the engine of my bikes til now

After all these years turning wrenches 4 a living

I guess u can teach an older dog a new trick

Well it gets hot here in Las Vegas Nv. so I run 20-50 Mobil one, year round.

Great, thanks, thought maybe some ran a little heavier oil because of heat. I am running 20W50 Redline now, looks like might stick with it.

Redline is top notch oil

I run their tranny fluid

I am using Quicksilver oil 20-50

Looks like it hits Mobil 1 pretty hard with a better additive package

I get NO clicking at all like my brother who uses Mobil 1

This would be a question you would have him answer,I personally don't see the advantage,but if it makes him happy.

Oil threads...I usually stay away from them.

A couple of thoughts.

20W50 & 20W60 oils are both 20 weight oil that have viscosity modifiers added to them.

The way that viscosity modifiers work is that the hotter the oil gets, the more these modifiers curl up and make the oil feel (pour) like thicker oil than the 20 weight that it really is.

Problem is that the viscosity modifiers get damaged by heat far more easily than the actual oil...as they get damaged, they don't curl up as much, so your 20W50 or 20W60 does not feel (pour) like 50 or 60 weight oil anymore...this generally happens way before 5000 miles, especially in hotter climates.

The above is the reason why Harley puts the following in the manual, and why many experienced mechanics recommend an actual heavier weight oil (not a 20W50 or 20W60) in hotter environments.

Scan from HD manual-



That said- I don't hesitate to run a synthetic 20W50, even in 100* temps. However, a synthetic 50W or 60W WILL provide better lubrication, last longer, generate Less blow-by, and make for a quieter top end.
