Two new gear lubes speed drive line service

Modern ring and pinion gear sets, whether limited slip or positive traction, require a final lubricant that contains both a GL-5 lubricant and a limited slip additive. These lubricants combined provide optimum drive performance and gear protection. Generally, they are added from separate containers increasing the chance for errors in treat ratios, which leads to more…

Under pressure: Low tension piston rings

In order to reduce frictional drag energy loss and increase fuel efficiency, gasoline direct injection (GDI) engines use thinner and lighter piston rings, called low tension piston rings. Piston ring spring force in older port fuel injection (PFI) engines used to be as high as 30 psi. New PFI and GDI engines can have more more…

Lab Q&A: PXT® transmission machine power supply

Question: Why does my BG PXT® just turn off sometimes? Answer: The BG PXT® Performance Exchange™ for Transmissions is designed to work with DC voltage between 11 VDC (volts of direct current) and 14.9 VDC with good power supply connections. If the charge is low or the connection is bad, the BG PXT® will not more…

BG EPR®: The best engine repair product is a maintenance product

I recently received a testimonial from a service technician in Wichita, Kansas. He told me his customer brought in a 2006 Chevy with 3.6L engine, and the oil light was on. It had been 15,000 miles since the last oil change! Her engine was completely sludged, and it actually sounded like a diesel. The technician more…

Lab Q&A: High Pressure Common Rail (HPCR) diesel injection systems

Question: Why do High Pressure Common Rail injection systems see more rough running engines, misfire, low power and increased emissions than traditional diesel injection systems? Do black fuel filters cause these problems? Answer: High Pressure Common Rail (HPCR) diesel injection systems are designed to produce significantly more power with reduced emissions due to closer tolerances, more…

BG PXT®: An evolution in transmission service

Back in 1997, BG introduced the first fully functional transmission fluid exchange system, the BG PF5. Sixteen years and nine models later, the BG PF5 is a rugged workhorse and has the ability to remove up to 90 percent of used fluid in a short period of time. With the BG PF5 cutting transmission service time more…

The Ethanol Problem

Ethanol creates hard deposits If a gas station is switched from conventional gasoline to E10, much of the sediment, oxidation residue and other contaminants in the storage tanks and lines can be dissolved or suspended in the new fuel. Contaminants can cause premature filter plugging and injector fouling. In addition to lost mpg and power, more…

Dual clutch transmission: Growing opportunity?

We are accustomed to two types of transmissions in all of our vehicles: manual or automatic. Manual is known for its strength and better MPG. Automatic is known for its ease and smooth operation. Today we hear more and more of a new kid on the streets that offers the best of both worlds: the more…

Lab Q&A: BG 332 vs. BG 334

Question: How do I determine whether to recommend BG Power Clean, PN 332, or BG Universal Synthetic Power Steering Fluid, PN 334. Answer: Many European and other import vehicles require a full synthetic “Mineral Suspension-Hydraulic” fluid. We often call this application a central hydraulic system. This fluid not only protects and operates the power steering more…

What’s bad for DPFs and why you should care?

All 2007 and newer, on-road diesel vehicles and 2010 and newer off- road vehicles are manufactured with diesel particulate filters (DPF). Many older vehicles have been retrofitted with DPFs. Tight emissions restrictions have caused diesel vehicle manufacturers to turn to after-treatment devices like DPFs for emissions reduction. What is it?  A diesel particulate filter is more…
