Q: Can I convert DF455 to electronic ignition? A: Yes. 123ignition makes a programmable distributor for the DF455 (part #123-RV-4). Highly recommended. renault df455

Q: What oil should I use? A: Modern 15W-40 diesel oil (like Shell Rotella) is perfect because it has high zinc (ZDDP) for flat-tappet camshafts. Do not use modern 5W-30. It will destroy your camshaft.

Q: My DF455 overheats. What is wrong? A: Most likely the radiator is original (50 years old) and clogged. Do not blame the engine. Recore the radiator. Do you have a Renault DF455 story or restoration question
