We organized an interview with the Motor Oil Geek. Specifically, we talked to Lake Speed Jr from Total Seal Piston Rings (www.totalseal.com), a lubrication expert who understands our cars, their specific needs, and--importantly--the chemistry behind the oil we pour into the crankcase! Check out his YouTube channel too!

In the 3rd and final part of our interview, we talk GL4 vs GL5 gear oils, synchronizers, and how the additive packages work in various applications. Whether you have a classic Mini or a Triumph TR6 with an overdrive, this video should interest you! We touch on lubricants for gearboxes and differentials, and what causes oils to break down in your engine.
