Diesel in Petrol help across Northamptonshire
Our technicians are out across Northamptonshire around the clock, covering Daventry, Rushden and Towcester and everywhere in between.
Diesel is oilier and far less volatile than petrol, so it will not ignite properly in a petrol engine. Expect misfires, heavy smoke and a car that cuts out, with the risk of fouled plugs and a clogged catalytic converter if it keeps running.
Breakdowns on the A14, A43 and A45 are reached quickly, and we attend lay-bys, services and car parks as well as forecourts.

Diesel in Petrol in Northamptonshire: FAQs
Is diesel in a petrol car as bad as petrol in diesel?
It's usually less damaging, but it still needs draining. Diesel won't burn properly and will clog the plugs and exhaust system.
I only put a little diesel in. Do I still need a drain?
Diesel nozzles rarely fit petrol filler necks, so if some went in, give us a call. We'll tell you honestly whether a drain is needed.
How long does it take in Northamptonshire?
Most diesel-in-petrol drains take 30 to 45 minutes once we're with you.
How quickly can you get to me in Northamptonshire?
Most call-outs across Northamptonshire are reached in 20 to 90 minutes, depending on traffic and where you are.
