This is an ideal oil for early model twin cylinder Yamaha XS650 that require a slightly thicker oil and can handle higher temperature ranges.

I have been using this oil in my classic motorcycle race engine for years. Synthetics burn almost as fast as the fuel. This oil is the most suitable I have found.

I have a single cylinder motorcycle. I started using this oil when the Yamaha warranty finished. I change the oil every 5000kms. It is now at 200 000 kms and still has good compression.

As a retired BMW mechanic I use this exclusively in my BMW's, it's the manufacturer recommended oil, for all oilhead BMW's.
Great value for a quality oil that gives added protection to my motor cycle engine from one service to the next.
I been using Actvi 4T in my Harley Davidson for years and it will not let you down. The engine is clean inside.
Great oil for all old and new thumpers. Great for Aussie conditions, keeps consumption down.
I have been using Castrol Active 4 T oil for many years , in a variety of classic Japanese bikes . Oils ain't oils , as you know . With so many oils , you need the correct oil , for your application . If you have classic multi cylinder , Wet clutch . This is great oil at a good price .
Now that you have asked. The Castrol oil went smoothly … However, Wed. 7/9 I ordered a pair of automotive bulbs via click & collect, upon picking them up they were the wrong ones, only to told I would have to go back on the Repco Web site and re-order and the guy just walked away a was more than disappointing, in fact I was furious, what kind of customer service is that !!!!PS> This experience was not in isolation, when I picked the Castrol oil up … the customer in front of me got the same treatmentTotal opposite experience at Autobarn … it’s Autobarn for me from here it is Autobarn ERINA for me!
I have been using this oil in my xr 250 since 2005, no problems whatsoever. Engine runs nice and smooth. Have used it in extreme heat under heavy off road, dirt bike riding conditions, I'm a big bloke, so the bike has to carry my fat butt as well...haha! No clutch or gearbox problems. I dirt bike ride regularly. Happy with Castrol 15w-50 4t activ oil, else I wouldn't useit. Cheers.
