Nissan Bluebird Engine Problems

IT'S time time you moved up to something more modern. The Bluebird is fine and won't cost a fortune to fix. Run the 180B on PULP or 98 octane unleaded.

ADVANCING the timing will exacerbate any pinging. Retard the ignition to eliminate it. LRP has an octane rating of 96, lower than the 98 super the Nissan would have been developed for, so try a 98 fuel. You don't need to add anything to LRP because it already contains upper-cylinder lubricant. On oil consumption, try to identify when the smoke appears. Is it when you start, accelerate, decelerate, or travel at a constant speed? If it's the rings, I would expect smoke to be there most of the time. Otherwise, check valve-stem seals or valve guides for wear.

If you think you've copped some bad fuel one way to fix it is to keep topping it up with good fuel as the fuel level drops.
