You can, but it will block your fuel filter quicker than it would if it was filtered down to 1 micron.adamr8965 wrote:Can you use oil filtered down to 10 micron's or does it need to be down to 1 micron?
Theres a place that filters down to 10 micron and selling it 35p a litre.
A fuel filter is 5-8 micron, so ideally you need to be below that. Some people filter to 0.5 or even 0.1 micron.
At 35p ltr be worth getting and filtering it further yourself.
