Typically, a multi-viscosity oil, such as 10W-30 or 20W-50, is recommended for various driving conditions. Additionally, the oil’s additive package is crucial. Flat tappet engines benefit from oils that contain high levels of zinc and phosphorus, known as ZDDP (zinc dialkyldithiophosphate). These additives help to reduce friction and wear, which is particularly important for the camshaft and lifters.
Another important parameter is the oil’s detergent properties. Older engines, especially those with flat tappet cams, can accumulate sludge and deposits over time. An oil with good detergent capabilities will help keep the engine clean and functioning efficiently. Furthermore, the oil’s thermal stability is a factor to consider. It should maintain its viscosity and protective qualities even under high temperatures and stress, which is common in performance applications.
Flat tappet cam oils are most commonly applied in classic cars, muscle cars, and vehicles that have not been retrofitted with modern roller cam technology. These engines are often found in vintage trucks and hot rods, where enthusiasts prioritize originality and performance. In these scenarios, the right oil not only enhances performance but also helps maintain the value of the vehicle by ensuring that the engine remains in good working order.
In summary, selecting the right engine oil for flat tappet camshafts is about understanding the unique demands of these older engines. By focusing on viscosity, additive packages, detergent properties, and thermal stability, auto owners can make informed choices that will lead to better engine performance and longevity. The right oil can mean the difference between a smooth-running engine and one that suffers from premature wear and tear, so take this decision seriously.
Choosing the right engine oil for flat tappet camshafts involves more than just picking a brand off the shelf.
