New Moto Guzzi Door Mats Available Now
Swede,I'm impressed that Redline got back to you w the data. I but the bullet and got some ZDDP additive. With that, I can buy a wider variety of oils.Especially since Guzzi dry clutches don't limit us to motorcycle oils, so we can get oils w friction modifiers. Joe
Redline makes a 10W-60 oil, and also a “motorcycle” 20W-60.I contacted Redline and they advised that their 10W-60 contains 1225ppm zinc and 1375ppm phosphorus, which they say is plenty of protection for Guzzi flat tappet cam and lifters.Just passing this along
I use Valvoline VR1 20w-50. 1300 ppm Zinc and 1200 ppm phosphorus. Bike seems happy.
This is what I switched to since I can’t find the eni/agitprop oil any more. On the shelf in most of the big box parts stores
I think Guzzi switched its recommendation to Castrol not too long ago. That is what my manual calls for.
Why do people call lifters tappets? They don't tap anything and if they do you have a big problem!
Guzzi recommends Castrol because BP pays for that recommendation.Why do people call lifters tappets? They don't tap anything and if they do you have a big problem!
Thank you for that. But, that begs these questions:What part did he call the tappet, and;Why don't people call roller lifters tappets? The reason I ask is all the tapping is done at the valve/rocker interface.Not a criticism, just curiosity.
Are you saying Guzzi's recommendation is wrong? Please enlighten me.
Try to get Castrol to tell you how much ZDDP is in their oils...Do they list it on their websites.
The big deal about ZDDP comes from hot rodders and racers running older tech OHV V8's. Open valve spring pressures can be 250 pounds or as much as 750 pounds...How much sping pressure is in a stock pushrod non high performance Guzzi? Generally a guy rebuilding a stock flat tappet engines used a High ZDDP break in oil and then a better mineral oil, nothing special...But proceed at your own risk... Oh, flat tappets are not flat and the damn things are lifters
