3 points of interest for this item.1. Ordering online was effortless.2. My instructions for where to place the item, should I not be home, was not adhered to.3. I would have expected (maybe my fault) that a 20L drum of oil would come with a tap.

Pros:Provides better engine protection for my high strung hot running motorcycle engine compared to semi synthetic recommended by manufacturer. What do engineers know, anyways...Tends to degrade less with erratic riding days and pauses enjoyed in our beautiful garden state.My Katombomb idels much smother since choosing this as the preferred poison over Jim Beam.Cheaper then motorex semi synthetic,But above all it's made by a great Aussie brand!Cons:$20 more expensive then it's full natural mineral cousin. But is it worth it? Absolutely, and so are you my beautiful friend!And before you ask, no the chepo diesel grog or high mileage car festrol will not do unless your motorcycle served in the great wars or you like your clutch 'slipping'.

This oil works well. I use it in my GSXR1000 race engine after previously using another brand, and it does what it is advertised to do.
The oil seems great. But suggest you do not use the silly filler that comes with the bottle. It leaks and keeps detaching from the bottle causing loss of your expensive new oil.
Perfect for my 2015 Yamaha R1M & now also in my 2022 Ducati Panigale V2 Troy Bayliss edition.
I've been running this oil in my race bikes for years (and will continue to do so); I have found it to be an excellent performer.
Quality oil my bike loves it full synthetic oil penrite ticks all the boxes and my bike engine noise is reduced as well.Port Lincoln store has amazing staff Jesse the manager served me and couldn’t have been more helpful
This is the 1st time I have purchased a Penrite product, as have mainly used Castrol and Motul oils, however, I had read several reviews about this product and it got top ratings. I bought motorcycle oil, but will be purchasing car oil and filter in the near future, and using Penrite again.
How do you rate engine oil without access to a laboratory?I can’t. But I am happy with this engine oil. I was riding when Adelaide had its 47 degree day and everything was within normal oprating range so it seemed to cope. Neutral is a lot easier to find, and clutch grab when cold (both known issues with this bike) are improved.So, no measurable evidence but it is my oil of choice. Oh, and it is Australian. I had some questions and posted on their website. A technician from their lab contacted me within 15 minutes and answered my questions. That’s good enough for me...
