Engine oil question

[Tiggsy]

Just taken delivery of a CRF 250 L and a 701 enduro. Both of them need an oil change after 600 miles and the recommendation for the Honda is 10-30 and for the 701 10-30.

Q1. - before the 600 miles up they will be taken to the Pyrenees and do approximately 1000 miles while there. So do I do the oil/filter change early? Do I do it early and then do it again on the return? Or something different.

Q2 - should I use the 30 rated oil for the Honda and 50 for the 701 or can I use one oil for both? And if so, which one? (Cost of the oil is not relevant)

Use same do early before the long trip

[Tiggsy]

If I’m using the same-do I use the 10/30 or the 10/50? Not really sure what the implications of using the wrong one for each bike is?

It's fine

The first number 10 is how well it pours cold basically. UK is fine for 5w or 10w

The second is how well it performs when hot. If you're giving it beans and ride in Spain run a higher number

For me I run 10w40 semi in my track bike and mx bike but change regular

I run bloody expensive 5w40 in my road bike as its what they use on services. Its overkill but the oil stays in 6000 miles at a time (although I probably put a litre between services where it burns it)

You be fine with 30w unless it's really hot and you're thrashing it all the time. If so I'd go higher

I'm sure I'll be told I'm wrong somewhere in all that but it's done me fine for 20 years

Spot on imho.

10w 30 or 40 will be absolutely fine.

Do you want to correct the OP? I'm guessing that for the 701 it should be 10-50 ?

How many miles are you looking at doing before the trip? Nearer 50 or say 400?

Personally I'd use the correct oil in each.

[Tiggsy]

sorry - typo in the opener. 10/50 in the 701.

Will get about 250/300 miles in before we leave.

I think I'll just buy 10/30 for the Honda and 10/50 for mine.

Put the right oil in each bike to start with after as many run in miles as possible, pre trip. If you're planning on taking a litre of oil to top up with as you're touring around, I'd probably just take the 10/50 with you to top up either bike. Or just buy oil out there if you need it

With that mileage, I'd do the oil change before you go - that should be enough to shift the majority of the material that the change is intended to remove.

x2 Id be holding out late as I could with that
