Can a 1976 Vauxhall Cavalier 1600 run on unleaded petrol? If not what can i do?

Question

I need to use the car regularly and hopefully keep the engine in good condition. Cheers folks!

Answer 1

Sure. Car won't care. Unleaded is there to protect the catilytic converters in cars that have that device.

Answer 2

Two points to consider. The octane rating of unleaded is lower, so some adjustment of timing is required regardless of additives used. The engine will have soft valve seats that relied on a coating of lead to protect them; regular use of leaded will have applied a generous coating of lead, which won't disappear over a few miles. If you intend to use it regularly you need to find a source of LRP or buy additives for each tank, which will be quite an extra cost.

Answer 3

vauxall were world leaders in making cars run on unleaded petrol but they were british and as the norm the british poeple knock what is there own in answer to your question yes it will run on unleaded petrol as vauxaul was miles ahead of other of other car makers but as is the british way they are gone sad but carry on buying your toytas renault fiat cirtroin but remeber your are keeping other poeple in work not the british

Answer 4

to be sure i would go to vauxhall and ask them as this is an old car
if it carnt then sorry new head as the vaves will burn out in the old head
but you may get one fron scrap yard of a newer model
as long as the enine is the same then it will fit
the bock is no problem its just the head

Answer 5

yes of course you can ...4star is just lead replacement fuel
i put unleaded in an old astra 1700 diesel and ragged it around a forest

Answer 6

it should be ok but if you are worried most garrages sell a lead replacement oil which you put in with the petrol
