can different brand of transmission oil used other then jcb expensive brand
JCB does not produce transmission oil. They buy it to their specification from an oil producer. Find out what specification or standard the JCB oil has... Then match the exact spec to another brand of oil. Beware the words "recommended for" or "universal" that doesn't mean it's the equal or meets the specification. It just means someone ? recommended it.
For mine, I pay $100 bucks for a 5 gallon pail. It's says it 10W oil.
180$ 11 litres and oil filter. down here
