60 W vs multi vs syn

I'm still running Valvoline straight 60 in my 77. Is everybody else still running the tried and true or have you changed to something else and what have been your results?

yep...60 wt in my '74 FL

BTW...I read that bit on Amer. Hot Rod crap...
you are right about no such thing as being safe in an industrial setting...
there is no safety...if you are there, it's dangerous...

You have a good point of view, in that regard, Flatheadrider.

thanks, appreciate the backup

Regarding Valvoline 60w, or any brand for that matter, is there a particular type of 60w that is more beneficial for a shovel? Racing oil, conventional, higher ash content?, etc I've been using a conventional Valvoline 50w but as the weather warms up I'll get some 60w. Thanks.

no answers / suggestions?

I used Amsoil 60W last year and it worked great. At a 1500 mile oil change it was almost as clean as new, where dino 50wt looked like tar. [u]BUT[u] when the temp dropped below 65 f it started to get REAL hard to start. This winter I changed to JIMS hydralic lifters and they reccommend 20/50 so that's what is in it now (Amsoil). No new leaks just a little seepage around the rockershaft ends. On my reccomendation my best friend put Amsoil 20/50 in his twinkie and he reports that it runs noticeably cooler. I like this stuff.

Thank you.

I've been using the dino grade 60 wt in the shovel and the knuck; syn 20/50 in the road king. Cold weather thickenning is not my problem; hot weather thinning is. Been considering going to the syn in the shovel. But the knuck? Old technology with old technology????

Guys,
Ya gotta remember something. For the most part automobile oils are made for water cooled autos. Not hotter running air cooled motorcycles. If yer gonna get cheap on oil at least use a deisel grade or oil for hot running turbocharged engines.

Yep, and that's why I asked my question above about specific types of oil, not the age-old dino vs synth or necessarily "weight" discussion.

You need to run oils that are certified for air cooled engines. In most cases those are racing oils or aircraft related. I'm not sure without looking it up , but I think it's SE rating. Valvoline Racing oil fits, Castrol GT, Royal Purple , Aero Shell, and Lucas oil. I usually run Valvoline Racing oil. 60WT in the shovel 20W50 in the Evo because it's readily available. I've had good luck with Castrol GT1. It comes in 70 wt which is good in 100+ temps. The evo runs great in any temps on the 20W50. Occasionally I add some Marvel Mystery Oil to clean out the system. Royal Purple claims to run cooler than any other oil. That's an attractive claim. I have rebuilt motors run on Harley oil, and Valvoline, and the ones run on Valvoline care much cleaner inside than the other brands of oil. I consider that a good sign.
We're taking a ride to Deadwood SD. next week (1500 miles round trip) for a family reunion and I'm going to switch to the HD Synthetic to test it. A lot of my customers run it and like it very well. At 10 bucks a quart it had better do very well. I'll post my thoughts after I get back.
