System 1 Spin-On Oil Filters


System 1  209-561B

System 1 has eliminated the need for disposable oil filters. Built from durable anodized aluminum housing, System 1 filters feature a washable, stainless steel element that can be used over and over again. These filters are able to capture particles as small as 30 microns, depending on the models. They can be completely disassembled for inspection, revealing metal shavings and residue that could indicate engine wear or damage. System 1 oil filters are perfect for daily drivers, fleet vehicles, and race and marine applications.

4 Common Motor Oil Myths and Why They’re False


The guys on Discovery Channel’s Mythbusters have exposed some pretty incredible myths.

But when it comes to debunking some of the most common motor oil myths, you’d be hard pressed to find a better source than Driven Racing Oil. Formulated by the engine gurus at Joe Gibbs Racing, Driven Racing Oil motor oil and break-in oil have protected Joe Gibbs’ 9,000-rpm, flat-tappet engines for over 500 miles of competition.

Those same Joe Gibbs engine gurus recently set the record straight on four common motor oil myths:

Finding Balance (Part 1): The Basics of Crankshaft Balancing


Machinists and engine builders have long been taught that, when balancing a crankshaft, its counterweights should equal the weight of the rotating mass, and equal half the weight of the reciprocating mass.

Machinists have used this formula to calculate bobweight for decades.

While this technique works extremely well for most street and race 90-degree V8 engines, the truth is it’s nearly impossible to balance acrankshaft perfectly. That’s because the balancer cannot account for variables like cylinder pressure, ring drag, rod length, counterweight phasing, engine rpm, stroke length, bearing friction, secondary vibrations, rocking couples, and static mass.

How to Use an Oil Filter Cutter — and Why You Need One!



Oil analysis.

If you’re an advanced DIYer, you’ve probably heard that term before. The proper nomenclature is actually “spectrographic oil analysis,” and it has been used for decades by oil companies, fleet operators, race engine builders, and others to measure the condition of engine oil.

During this analysis, the user sends a sample of oil to a spectrographic analysis laboratory, such asBlackstone Labs, where a portion of the oil sample is run through a spectrometer. That device analyzes the oil and gives the levels of the various metals and additives which are present in the oil. Those levels are a measure of how much your engine is wearing.

Vac Visual: Quick Guide to Vacuum Gauge Readings


Intake manifold vacuum is a key indicator of engine performance.

By measuring vacuum under different engine loads and conditions, you can track down problems within your engine and make the necessary adjustments or repairs. The key is having a reliable engine vacuum gauge and then knowing how to read it properly.

We’ve said it before, but an engine vacuum gauge is an extremely valuable tool. It’s so valuable, in fact, that OnAllCylinders contributor Lori Sams put together this visual cheat sheet to help you understand common gauge readings.
