How often should I use the Petron Oil Additive when changing my oil?
We use a full 12 oz. bottle of Petron Plus 4-Cycle with every oil change here at Brock's Performance. This is especially true in bikes that are trying to achieve their best times/highest speeds and/or produce max power on the dyno. Petron treats the metal, that's the insurance part of the product, in case the pick-up is ever starved for oil (wheelie/hard launch or extreme decel at the end of a run, etc.) But, Petron can't reduce the coefficient of friction in the oil and treat the metal... if it isn't IN the oil.
For general street use, we use 3 oz. per oil change. That's 4 oil changes per bottle for a measurable increase in power as well as the increased peace of mind.
Below is an image of a 230+ HP land speed BMW S1000RR connecting rod bearings after teardown. Why the teardown? The rider bottomed out the suspension during a 1.5 Mile LSR run and severely broke the oil pan (the entire drain plug and area around it was broken off.). He didn't realize he had broken the pan (which immediately began gushing oil), only that it was time to abort the run after he felt the 200+ MPH impact disrupted the chassis. He continued to the end of the shutdown area (@1 more mile...dripping all the way), bypassed the timing booth and rode the bike all the way back to his pits.... the oil track could be followed the from the time of impact. At the pits...only a few drops were left to fall. His crew asked him what all of the smoke was about?! His engine builder, assuming the worst, called it a weekend and brought the bike back to the shop for a complete teardown. To his amazement, there was NO damage...anywhere. Cams/rockers/pistons/cylinder bore was all fine. The connecting rods bearings would typically be the first failure in a zero oil pressure situation of this nature, as you can see from the image below, they could have gone back into the engine. They were replaced as a matter of protocol and the bike went on to travel 221 MPH at the next event and made 20+, event-free, 200 MPH runs that weekend.'
