Hello everyone! I am new to the forum and i'm overwhelmed with all the information here, so much to learn! I have tried doing some searches but they either seem to be a little to technical for what i am looking for, or just dont contain the right info. I just rebuilt my Chevy 250 l6 engine. From what i have heard, synth "works too good" for break in so you should use dino oil. With so many oils on the market, what would you guys reccomend for the break in lube? From what i have read here so far, gm engine oil supplement would be a good idea for it's moly content for first firing/cam break in and maybe through first few oil changes. Then later i would like to run synthetic because i dont think leaking will be a problem with all brand new seals
. So, what i need is some reccomendations for a good dino break in oil and a good synthetic to switch to after break in. This will be in my '66 Chevy BelAir and i'm in ohio if the climate matters. Also will run a 180degree thermostat. Thank you so much for your time and i look forward to learning alot from you guys.
