How to use the Product
Once you’ve installed your Genuine GM 350ci / 5.7L Gen 0 engine into your vehicle you’ll need to break the application in. Breaking the engine in is standard for new applications.
Step 1
To perform an engine break-in simply use non-synthetic oil for the first oil change. Before changing the oil, check the fuel level and prime the oil system with a priming tool designed for engines. This break-in procedure is meant for flat tappet hydraulic cams only.
Step 2
Now run the engine between 2000 and 2500RMP with no load on the engine for the first 32 -minutes. Running the engine with no load at this time is crucial to break-in the camshaft.
Step 3
Drive the vehicle with altering speeds and loads on the Chevy engine for at least 30 miles & don’t use a lot of throttle or high RPM during this step.
Step 4
Run five medium throttle accelerations to 3000RPM at 20MPH to 50 MPH. Then ease up on the gear to go back down to 20MPH. Run a few hard throttle accelerations of 5000RPM at 55MPH to 60MPH and then go back down to 20MPH.
Step 5
Now park your vehicle and wait for the engine to cool so you can change the oil & filter. Remember to check your coolant level and top it up if it’s running low.
Step 6
Drive the next 600 miles normally without high RPMs. Keep the RPMs below 5000 when you drive. After the first 600 to 1000 miles change the filter and oil to a non-synthetic product & keep checking the engine fuel levels during this time.
You can use synthetic oil in the engine after you’ve changed the fuel for the second time.
