It will take me a long time to get 1,000 miles on the new engine. How soon can I change it?
Also, any problems with running synthetic oil? |

QUOTE(Type 47 @ May 29 2026, 09:43 AM)  It will take me a long time to get 1,000 miles on the new engine. How soon can I change it? Also, any problems with running synthetic oil? Too long ,as mentioned, 500 miles is plenty if the motor driven to "run in specs" which means limited idling and constant load changes on the engine to assist the rings to "bed in " ,avoid constant high RPM . Engine tune is real important BERORE running after a rebuild ,timing and fuel if wrong can do a fair amount of damage in a very short time...seen it . Not a fan of synthetic oil used in old design engines, quality dino full zinc 20/50 has served me well in T1 and T4 motors ,cheers. |
