Gasoline11
  • The idea was that the tetraethyl lead in pre-1970s era gasoline protected valve seats by depositing a coating of lead, or lead-oxide. (secondchancegarage.com)
  • Oddly enough, the number of valve seat failures in engines using Amoco unleaded gas in the 50s and 60s were no greater than in those using leaded gas, so it logically follows that valve recession was a function of other engine defects and not the type of gasoline used. (secondchancegarage.com)
  • These classifications use either an "S" prefix which means gasoline engines or a "C" prefix which means diesel. (secondchancegarage.com)
  • it does not need a fuel-oil mixture, but regular gasoline. (wikipedia.org)

  • Unprotected valve seats eroded away in some engines, a condition known as valve recession, and unleaded gas was blamed. (secondchancegarage.com)
  • Most automotive engineers will tell you that valve recession normally occurred as a result of extended high RPM operation or under extreme loads and had little to do with the valve seat material. (secondchancegarage.com)

  • The only thing you can hope for is that the particles of the central electrode managed to slip into the exhaust system without being stuck under the exhaust valve, otherwise the cylinder head repair also cannot be avoided. (arkheno.com)
Petrol2
  • Lead alternative petrol (LRP) was developed for autos designed to run on leaded fuels and incompatible with unleaded fuels. (myotherbardenver.com)
  • The object of the higher compression ratio is to take advantage of the modern petrol fuels with high octane values (see the chapter "Modern Aero Engines" ). (wondersofworldaviation.com)
Mixture4
  • What you're hearing is pre-ignition, which occurs when there's a pocket of fuel/air mixture that's igniting ahead of the flame front from the spark plug. (advanceautoparts.com)

(avweb.com)
  • The cause of this destruction could be one of the following factors: prolonged operation of the engine with detonation, the use of fuel with a low octane rating, very early ignition, and just a defective candle. (arkheno.com)
Stabilizer2

Oils4
  • The internet is full of anecdotal stories about the effects of using new lubricating oils in old engines. (secondchancegarage.com)
  • Newer oils have vastly improved oxidation resistance, deposit protection, wear protection and low-temperature performance over their service life, which means that they should perform better than older oils in any engine. (secondchancegarage.com)
  • Engine lubrication oils have chemical compounds or additives added to them for improved performance. (secondchancegarage.com)
  • Although the 100LL avgas is refined to meet the industry standard ASTM D910, the FAA's own guidance says an independent specification for fuels and oils is specifically allowed, Braly said. (avweb.com)
Compression3
  • Some of these effects are real (fuel system gasket failures and a lack of power in very old, low compression engines) but most aren't. (secondchancegarage.com)

Cylinders1
  • This will cause gums to build up in the engine cylinders, as well as the fuel lines, which makes it harder to start the engine. (motorcycleintelligence.com)
Engine's2

  • Improve your engine's power output level by running the required grade of fuel. (klmperformance.com)
Ignition3
  • Especially for the German market with its then road traffic licensing order (StVZO), the engine with a speed limiter was provided, which together with populated spark plug, the preset ignition timing, the carburetor and the translation of everything delivered Standard allowed only a maximum speed of around 40 km/h. (wikipedia.org)
  • On an older engine where the ignition timing could be adjusted, knocking could be addressed by retarding the timing a little. (advanceautoparts.com)

Piston2
  • In extreme cases, knocking can result in catastrophic damage to the engine, including cavitation or even perforation of a piston crown. (advanceautoparts.com)
  • The reason for this is the destruction of one of the valves or the breakdown of the partitions between the piston rings with the ingress of metal particles between the valve and its seat. (arkheno.com)
Time7
  • Therefore, with this alternator under this driving mode, especially in the case of predominantly short-distance traffic, the optimum charging of the standard accumulators (on-board battery 6 V, 4 Ah) while driving no longer guaranteed, which may lead after some time with each 21-watt bulbs (6 V) operated turn signals lose their function. (wikipedia.org)
  • Ensures your ability to obtain High Octane Race Fuel all the time. (klmperformance.com)

Work5
  • Shell has since stopped public work on a replacement fuel and Swift exited PAFI. (avweb.com)
  • The agency invited GAMI to join the PAFI program but the company declined because the program didn't allow changes to fuel blends to meet test requirements during the program and because the FAA refused to credit GAMI for test work it had done in the four years prior to PAFI's establishment.
