A car I’m getting soon has a new (1400 mi.) 530hp LS3 crate engine from them. I always thought that after initial break-in, 500–1000 (tel:500%E2%80%931000) miles would be good to go full synthetic.
Here’s the quote off BluePrint’s website.
“This break in oil can be used for the first 500 miles, during the break in of your new crate engine. It has been specially formulated with the following benefits to break in your new engine and get you started with all the proper additives to ensure a long engine life. The benefits of our break-in oil are:
Increases high-temp film strength, oil pressure and compression at all RPM ranges. Designed to reduce potential engine failure during the break-in period. Provides high-temp viscosity and anti-wear control. Protects bearings at initial startup and at higher speed and temperature. Recommended for all types of engines: including flat tappet and roller camshafts. Requires no additional additives.
If you wanted to source oil locally for your crate engine, we just want to make sure you are using a good quality oil – we typically recommend a 10W30. Also, if you are running a flat tappet camshaft please make sure you are also using a separate zinc additive, in addition to your oil. Refrain from using synthetic oil for the first 9,000 miles on all BluePrint crate engines.”
