My opinions on microblue ...

[mj9770]

I did the Micro Blue thing on an N-14 rebuild. Also trans and wheel bearings were done. It took a long time for that engine to quit using oil. Right around 100,000 km before oil consumption hit a gallon in 300 hours. With all those things “coated” you couldn’t tell much in fuel economy. But when truck was dyno’d at Cummins Edmonton it put 503hp on the ground out of a stock 525. The dyno tech said it was the strongest N-14 he had seen. So. If asked if I were to spend the money again? No. Never seen enough real world gains. If it’s true that it does what they say? Not sure. Could have been the low rolling resistance tires that put the power to the ground.
