4RT semi or fully synthetic engine oil?

Featured Replies

Chaps,

lanning on doing my first oil change this weekend, just bought a filter and some Castrol Power 1 10W-40 4T...

But just noticed it’s SEMI not FULLY synthetic.

is this a problem? Should I go back and swap it over?

cheers Boner.

Shouldn't be a problem.  You may need a gasket for the casing as well, they tend to stick and tear.

By sheer chance I found this while looking for something else Oil

That’s quite an interesting read.

Not 100% convinced...

went and bought some Fully Synthetic just in case!

Hey boner 

I’ve had a 3 4rt’s always ran them on Castrol power race fully synthetic without any issues. Fairly sure the manual specs 10w 30 for the 2014 onwards bikes. 

 

 

 

You did get some transmission oil as well I hope?  Engine and transmission are separate just in case you don't already know.

Buying some Elf for the transmission tomorrow. ??

Yes if you're using Castrol Power 1 the 'Racing' branded one is the fully synth.

Occasionally pops up in Tesco's garages at £3 a litre, always worth a quick glace if you're in paying for fuel.

What are you all paying for the Elf tranny oil?  Here in the US, takes a couple of weeks to get it through our Honda dealers, and $50 USD per quart/liter.  Literally black gold!

I would contact Dennis at https://www.overlandtrail.biz/.  He is your man for getting the ELF oil for you, as well as other parts.  Sorry I don't remember what it cost me for my last oil change but he usually stocks some so should be able to get it to you in short order.  (FYI: No affiliation, just great services from him over the years!)

Thanks!  Will check him out.
