Look at thev specs, if it meets the spec for your John Deere it will be fine.Mini update: got prices for oils
Hyguard £650
Millars £450
Exol £400
And 15w30 (god knows what make) £390
Vast differences.
are Millars/Exol good enough brands. Will work out as cost effective to stick to 20ls as go for hyguard in both.
and 1 stupid question, do I need to drain all oil before putting in the hyguard equivalent to the Ford or is it ok just to keep topping up?
You don't need to drain the Ford
