That’s great. Thanks! Sounds like zinc is our friend, unless there’s a cat, and if I had a bike that new I’d probably be running Motul synth oil in it, or something like. Cool! Be sure to get your daily recommended intake of zinc!
I just ordered a case of the Valvoline 60w for my '79. Have the clutch apart for cleaning and adjustments.
Does the Lucas affect the clutch if any of the primary oil gets on the clutch discs? I have always been concerned about that in the primary.
My metal clutch discs look kind of rough and I was trying to find good replacements. Is there a 'go to" for those?
Thanks for all the advice Johnjzjz, it has helped my with my bike more than once
buy the steels with out the ball and springs - we only use the red alto clutch discs and soak them in ATF over night and wipe them off good - i also use the alloy end clutch plate set the springs to 3/4 of an inch i use a nut that is that long and a plastic ram just retainer to hold the center clutch hub in place when you pull the clutch in - we also iso the primary with 8 oz and only use the 60 weight BUT i have never seen the clutch we use not like the oil or the Lucas
Cool! Be sure to get your daily recommended intake of zinc!
I think it needs a little salt... I may take a look at AMSOIL at some point. I do not know a lot about it but would like to use full synthetic in the air cooled engine because it can take higher temperatures. MY 2021 FLHR has a cat. right now. Diesel engine oils are supposed have a lot of zinc in them also.
No matter what when you talk about oil - bible thumpers are only 10 percent the crazy the oil home owner experts that show up - with the ideas they have
I know on most of the british bikes I have owned over the past 45 years I would use Castrol EP90 gear oil,
nice n thick & works very well,
but on Harleys I always use the same motor oil as is in the motor as the manual states & have never had a problem other than a few minor leaks,
I have always wondered if using EP90 or even EP120 would be good in a Harley Trans to help stop the minor leaks, or if it would be too thick for them when it comes to starting on a cold day or for gear selection,
has anyone here ever used EP90 in a Harley 4 speed ???.... would love to hear any Pros & Cons to it if you have....
I am sure it works for what your using it as they both the machine and the oil is a local product
gear oil in the USA is rated for its qualities in metal useage used - GL4 is to be used for brass components like bushings and in cars a synchro ring and thrust washers ( reverse )
GL 5 is all steel trans no brass and is corrosive to brass SO ——— EP in Europe is on its own no one will know in the USA Today what they are doing in the dyster stock mix
I still use Brad Penn/Penn Grade in my Shove and Flathead motors, for the zinc. I like the 60wt for both, also easier to have a common oil for two bikes. I have used the VR1, no issues and seems to be a little easier to source. I get Penngrade from Jeggs, I just buy it by the case.
Synthetic in an older bike is a good way to find new and different oil leaks, my opinion.
I’ll be using the VR1 60w with some of the Lucas Heavy Duty Oil Stabilizer added, but just for fun I ordered a quart of the PennGrade 1 gear oil from a motorcycle engine shop in North Hollywood, California called F&G Engine. This shop seems to specialize in vintage British bikes, and my impression is that for old Triumphs and the like this is the oil of choice. I’ve attached pics of the bottle and the literature and extras that the shop included with the oil. It emphasizes the oil is good for gearboxes with yellow metals. It was nice of them to include the postcards of the old Triumph race bikes, and it’s nice to do business with a small shop of motorcycle enthusiasts. Hopefully this sheds more light on this lesser known oil and I hope you may find interesting.
I am curious what is the weight / viscosity of the Lucas Heavy Duty Oil Stabilizer? The bottle recommends adding 20% - 60% total volume depending on the condition of the engine or gearbox. How does this mix effect the oil’s weight / viscosity?

Judging by the Brad Penn literature EP whatever number is a no no where GL-4 is indicated.
The British drink warm beer because they own Lucas refrigerators - no one cares what triumph did or does
the Harley factory shop service book sayes what ever you use in the engine use in the trans - but we see bikes that no one knows how to read apparently
