I've put some diesel in my petrol car by mistake will it do any damage? What is a safe amount?
It depends on what you mean by 'some diesel'. As a safe amount the industry generally accepts 5% or less of diesel in petrol is OK.
When you work it out for your tank capacity you will soon realise it's not a lot of the wrong fuel before it's too much. See the table below for a
guide.
If you don't know your tank capacity then give us a call on 01472 867070 for free advice or google your vehicles tank capacity but do be
careful as the tank capacity can vary by year, model of car and engine size.
If you have gone over the safe amount the likelihood of damaging your engine is minimal as diesel is a less aggressive contamination but
that doesn't mean it's OK to put more in than the safe amount. If the engine will start then it will be strained as the diesel in a hot engine
will combust too soon and the engine will run hotter than designed and potentially damage the pistons etc.
If this pre-ignition (pinking) is occurring get it sorted immediately and do not undertake any long journeys or travel above 30mph. Self
imposed limp mode and seek help as soon as possible is the best advice.
Depending on the quantity of the wrong fuel, exceeding the safe amount will at least cause one or more of the following symptoms:
•
Prevent the engine starting easily from cold
•
Loss of power
•
Rough idling
•
Engine will stop after a short distance and not start again
•
Cause the engine to run on after the ignition has been turned off (Pre-ignition)
At worst being able to drive with too much diesel in the petrol will cause:
•
Pre-ignition or engine knock which if not cured can lead to -
•
Damaged pistons, valves, crankshaft and bearings
•
Contaminate the catalytic converter in the exhaust system and need to be replaced

I've put some diesel in my petrol
car by mistake will it do any
damage? What is a safe
amount?
It
depends
on
what
you
mean
by
'some
diesel'.
As
a
safe
amount
the
industry
generally
accepts
5% or less of diesel in petrol is OK.
When
you
work
it
out
for
your
tank
capacity
you
will
soon
realise
it's
not
a
lot
of
the
wrong
fuel
before
it's
too
much.
See
the
table

for
a
guide.
If
you
don't
know
your
tank
capacity
then
give
us
a
call
on
01472
867070
for
free
advice
or
google
your
vehicles
tank
capacity
but
do
be
careful
as
the
tank
capacity
can
vary
by
year,
model
of
car
and engine size.
If you have gone over the safe amount the
likelihood of damaging your engine is minimal as
diesel is a less aggressive contamination but that
doesn't mean it's OK to put more in than the safe
amount. If the engine will start then it will likely
stop after a short while as the diesel is too cold to
ignite and therefore wets the plugs and stops
them from sparking. If there is enough heat in
the hot engine and it continues to run the engine
will run hotter than designed and potentially
damage the pistons etc.
Depending on the quantity of the wrong fuel,
exceeding the safe amount will at least cause
one or more of the following symptoms:
•
Prevent the engine starting easily from cold
•
Loss of power
•
Rough idling
•
Engine will stop after a short distance and not
start again
•

has been turned off (Pre-ignition)
