Toyota Corona 1982 Q&As

Check out real-world situations relating to the Toyota Corona here, particularly what our experts have to say about them.

• Additives work best

  CHECK the engine is a Toyota engine because Toyota was fitting the Holden 1.9-litre overhead-valve four-cylinder engine to the Corona at that time. The capacity you quote suggests yours has the ``misfire'' four in it. If it's a Holden engine the compression ratio was 8.7:1, but it's likely to be less than that now. If it runs well I'd continue to use unleaded with an additive.

• Losing lead

  ACCORDING to the government guide, your car cannot run on unleaded petrol without an additive, so the best advice is to run it on regular, or premium unleaded if you can afford it, and add a commercial lead replacement additive available from your servo.

• Going over the top

  YOU can cause a problem putting too much oil in the sump. The crankshaft hits the oil as it rotates, which can put extra load on the engine, reduce performance and increase fuel consumption. It can also cause the oil to froth and cause problems in the lubrication system. However, adding an extra 200ml probably won't have too much effect.

• Fuelling options

  I haven't heard of any problem in getting LRP in your area, but I will check with the fuel companies. The engine in your Toyota should have valve seat inserts which means you could simply switch to ULP without the need to use an additive. PULP would be a waste of money in your car when it will run happily on regular unleaded.
