That film is either up to the job or it isn't, and there's no middle ground at 1,000 degrees of turbo heat. Doc's Full Synthetic Heavy-Duty Diesel Oils are engineered for engines that earn their keep: maximum wear protection in severe operating conditions, from brand-new emissions-compliant rigs to the high-mileage workhorses that refuse to quit.\u003c\/p\u003e\n\u003ch3 style=\"color: #af3939; font-weight: normal;\"\u003eBuilt for Severe Duty, Not Just Rated for It.\u003c\/h3\u003e\n\u003cp\u003eAvailable in 15W-40 and 5W-40 full synthetic formulas, Doc's oil delivers an advanced additive system that protects critical components under high-load, high-heat conditions, excellent low-temperature pumpability for fast cold-start protection, and enhanced oxidation and thermal stability that fights sludge and deposits.
