I recently had my intake manifold gaskets on my 98 chevy 5.7L replaced due to an internal coolant leak. The truck was filled with 5W-30 Chevron Supreme after the repair.
1. Should I add AutoRx or Lube Control to this oil change in case there is some residual coolant in the oil.?
2. Should I do an oil analysis on this oil change to see if the leak is in fact fixed or should I do one on the change after that in case there is some residual coolant in the oil from the repair itself?
3. How many miles should I go before having the analysis done. Thanks for any input.
