Learn about ZDDP levels in motor oil and their importance for engine protection.

760 views

ZDDP (Zinc dialkyldithiophosphate) levels in oil typically range from 800 to 1400 ppm (parts per million). This additive is crucial for protecting engine components by providing anti-wear properties and oxidation resistance. Higher levels are found in oils meant for older vehicles or high-performance engines, where wear protection is especially important.

FAQs & Answers

  1. What does ZDDP do in motor oil? ZDDP provides essential anti-wear properties and oxidation resistance to engine components.
  2. Why is ZDDP important for older vehicles? Older vehicles often require higher levels of ZDDP for better wear protection due to their engine design.
  3. Are there oil brands with high ZDDP levels? Yes, many high-performance and specialty oils offer elevated ZDDP content tailored for older and performance vehicles.
  4. How can I check ZDDP levels in my oil? You can check ZDDP levels through laboratory analysis of your oil sample or by reviewing the specifications provided by oil manufacturers.
