Toyota Problems

TOYOTA had an LPG-compatible engine for the Avalon when it was selling it to the taxi industry, but the LPG industry tells me there are no problems running the regular Avalon engine on LPG either. For an installer, contact Apollo Gas.

The 1983 Cressida was designed to run on leaded Super when new, so should be run on LRP lead replacement fuel now. LRP has an octane rating of 96 which is slightly lower than the 98 octane Super available before 1986, but should still be the best bet for your car. If you hear the engine pinging on LRP, it's a sign it needs a fuel with a higher octane rating. If this happens you could then add a commercially available octane booster which will fix the problem.
