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:
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.
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.
