Title: Mineral oil and change routine.
Post by: Athame57 on February 26, 2024, 07:58:42 PM

The 10W40 mineral oil we are supposed to use I gather has a much shorter life than synthetic oils, but we do have rather large sumps. How often do you change your oil?

I work to Honda, every 1500 miles or once a year whicher comes first
Honda say filter every other change but i do it every change.

The size of sump and mineral or synthetic dont matter a stuff, its the gearbox and rich carbs wreck the oil!

I change my 400 oil every year as I have not yet covered close to 1000 miles.

I change mine every 1,500 miles, I do about 2,000 miles a year. Strangely though last time I changed it I couldn’t get anything like the 3-5 litres drained out of it.

I didn't know they exist until now, I'll be looking around their website later. I've settled on Westway 10W-40 4T, a teeny little bit more expensive at £31.99 for 5 Ltr.
