so i have a 4.7 v8 that was installed about 2500 mi ago, and i changed the factory oil at 1500 mi. i replaced it with QSGB and a cheap filter and will be doing the next change at 3k on that oil which had 1k on it. the engine manufacture said to run dino for 7k or it will blow syn out the tailpipe. i would do listen to his recommendation, but i have a ton of the PP from the fuel rewards, and want to dive into the stash. are his concerns valid, will i blow oil out the exhaust? if i do ca i go back to dino until the truck is ready? thanks
