I used to use Mobil 1 V Twin in my HD M8 114 but the top end noise was crazy. I have the Penrite MC 4T 20w50 V Twin in the engine now and it's amazing how much quieter the engine is. I'm so happy with the performance of this oil that I'm now using the MC 4T 10w40 in my primary and the Pro Gear 75w90 in the gearbox. All the oils are full PAO Ester oils which means these oils are top of the line.

If you have an Air-cooled V-Twin, this is the best oil you can put in it, fully synthetic, which is of vital importance in high temperature areas like Northern Australia, as a full synthetic oil will keep its viscosity in the extreme heat we experience. Don't risk any other oil in your Motorcycle. Highly recommended.

Had a noise in 2005 VTwin Vulcan VN800.Was using 10W40 but it just doesn't cut it in the tropics of Darwin.Clutch slip, noise and knocking.Put a high flow oil filter and the VTwin 20W50 and all those issues went away.Expensive, but not all oils are created equal.Definitely recommend for the old VTwins out there.

I used this product as I use a lot of Penrite products and never had a complaint. My local HD store was closed so I thought I would give it a go. I have been running it my HD V-Twin now for about 2 weeks with no problems or hiccups. 4L was the perfect amount to do my primary, and engine oil. I will use it again at the next service.
Penrite is my go to oil. Use it in all my bikes. but Over priced at $104 for 4L I used price match as Autobahn has this same item at $84 and on sale for $71. Just something to look 🤘
Penrite oil gives me confidence that I’m using a good quality oil from a local company. The Penrite synthetic oil doesn’t blacken up over the life of an oil change even in an air cooled engine where high temperatures break down an oil. I’ve been using Penrite oil in three different motorcycles, all air cooled.
Has all the modern synthetic technology with high levels of zinc to protect and thoroughly lubricate my air cooled classics in the hot climate of central coast of Queensland.
I use this oil on my DL1000 V-Strom. The bike runs beautifully. I believe this is a quality synthetic motorcycle oil.
Cant go wrong with Penrite its Aussie owned so my money should stay here and give Aussie jobs not chineseIts good oil i use Penrite in all my vehicles including premium mineral mono grade in my old bikes they love it i have using it for decades never had a problemWhat more can i sayBuy it and keep Australia goingRegardsScud
Used it for my Harley Davidson Fatboy. I could tell the difference on the first ride. The bike runs smooth and engine noise was reduced significantly. Will use again. And definitely recommend this for similar motorbikes
