hello all i know this has been asked before so im sorry to ask again.  My local HD shop is closing down and ive been using harley oils in my 2020 heritage eg engine syn3. trans and primary formula plus. i was thinking of going to penrite MC-4ST Vtwin 20w-50 in the engine only not sure about trans and primary what would you guys out there recomend or what are you guys  using thanks again Pete

Everyone has their favourite oils of various brands Pete, if you go to the Penrite oil finder and punch in your bike details it will tell you what they recommend(pretty sure that will be the oil you mentioned in all 3 holes)same for most oil companies, I use what I use based on where I live and what I think I know.

I use the Penrite MC-4ST (syn) in my '22 LowriderS for the engine, Belray's Primary Chaincase oil for the primary (non syn recommended by my tuner) and Redline Shockproof heavy in the g-box- This is just what I use HD oil's are ok but you can get better non HD oil for less 

Penrite for me. Every thing is local . As mentioned , go to their part finder for your bike etc...

Penrite recommend the oil in the pic for all 3 holes in your 2020 heritage. (All full 100% synthetic)....

"NO SUBSTITUTE ALLOWED" Dontcha just love that bollocks ?

reckon i got a dose of " emu piss " on the way to the alice in the late 80's [ 1000 suzuki ] ran like shit for a bit.....lol

I brought my first Harley from Goldfields Bikeworks in 1996, Brett was still in the old shop then, the new one had yet to be built, he got the shits with HD I heard, don't know if he is still the proprietor these days, shame it's shutting, long way to the next dealer unless another shop there picks it up, given the money in that town it's hard to imagine it's a lack of sales thing.

brought the FLSTS heritage springer new of Brett at the Goldfields bike workshop back in 1997 and a lot of bling over the counter
