Fluid Care Technical Library
Whitepapers and articles on hydraulic oil contamination, varnish, diesel quality, and condition-based maintenance. Technical backing for your operating decisions.
The one-minute lubrication inspection: what to check every day
What to check daily in one minute: oil level, sight glasses, breathers, filter gauges, leaks. Preventive maintenance that catches failures early.
Latin American Diesel Is 2,000x Dirtier Than Your Engine Can Tolerate
Latin American diesel averages ISO 4406 22/21/18; common rail engines need 11/8/7. What the gap costs and how tank-side diesel fuel filtration closes it.
The ROI of contamination control: what dirt costs you every year (and how to calculate it)
Calculate what oil contamination costs you every year: a fillable worksheet, a fully worked example, and why contamination control pays back over 4:1.
Bypass filtration vs. varnish: why in-line filters do not protect your servo valves
Modern servo valves operate with clearances of 1 to 3 microns, yet most oxidative varnish is smaller than 1 micron: in-line filters cannot capture it. This whitepaper explains how varnish forms, why full-flow filtration cannot stop it, and how a slow-flow bypass loop removes it without shutting down your operation.
The gap between NOM-016 and NOM-044: why commercial diesel damages Common Rail engines
NOM-016 regulates the physicochemical quality of diesel but does not require an ISO cleanliness code. NOM-044 mandates engines whose injection systems cannot tolerate that contamination. This whitepaper explains the gap, its real cost in injectors and filters, and how to close it with coalescing filtration at the bulk storage tank.
Five signs your hydraulic oil is oxidizing (and how to stop it without CapEx)
Hydraulic oil oxidation is a silent enemy: by the time it is visible to the naked eye, the damage is already advanced. These are the five early warnings we look for in a fluid audit and what to do when they appear.
