Lab Q&A: BG 44K® and BG 244

Question: Why can’t I use BG 44K® in diesels? Answer: Many have used BG 44K® in diesels but it is specifically formulated for gasoline engines, which don’t reach the same temperatures as diesel engines. Because diesel engines run hotter and at higher compressions, they must withstand stresses far beyond those in gasoline engines. BG 244 more…

BG solves sticky situation in gasoline direct injection engines

In the article “Gasoline Direct Injection” in the Winter Issue of the Blend’r, we uncovered the disadvantages of the gasoline direct injection (GDI) engine: Dramatic efficiency losses due to deposits on the piston surface More deposits on the intake ports and valves (compared to port fuel injection engines) Low-mileage misfire codes Fuel economy loss Disadvantages more…

ZDDP: What does it mean to me?

“Oil is killing our cars!” warns Keith Ansell, President of Foreign Parts Positively. “Be aware that ‘New and Improved,’ or even the ‘standard products’ we have been using for many years, are destroying our cars. It isn’t the same stuff we were getting even a year ago.” Although a bit of a sensationalist, Keith is more…

Lab Q&A: Diesel Exhaust Fluid

Question: What is DEF? Answer: Diesel Exhaust Fluid (DEF) is a nontoxic, urea-based chemical reactant necessary for the functionality of Selective Catalytic Reduction (SCR) systems, which reduce oxides of nitrogen (NOx) emissions. Most major engine manufacturers are using SCR systems to meet 2010 emission regulations. Here’s how it works: DEF is injected into the hot more…

Gasoline Direct Injection

Way back when Gasoline direct injection (GDI) was first used in 1925 on the Hesselman engine. Jonas Hesselman designed the engine to start on gasoline and then switch over to run on diesel or kerosene. But in 1952, Bosch developed the first automotive direct injection system that actually ran on gasoline. Mercedes Benz wasn’t far more…

Lab Q&A: Continuously Variable Transmissions

Question: Why do we need a new CVT Conditioner if BG’s CVT Fluid offers unsurpassed wear protection? Answer: BG Universal Synthetic CVT Fluid, PN 318, is designed for use in only belt-driven CVTs. These CVTs exhibit modest thermal stress and require good surface-to-surface metal protection. CVT units produced by GM, Chrysler, Nissan, Mercedes Benz, Subaru, Lexus, more…

What you need to know about ethanol

Does the use of ethanol reduce fuel economy relative to conventional gasoline? Yes. The consumption of fuel relative to miles/kilometers traveled is directly related to the energy content. Conventional gasoline has an average energy content of 114,000 BTU/gallon. But, energy content of conventional gasoline can vary up to 7 percent from one fill up to the more…

Lab Q&A: “Synthetic” Products

Question: What makes a product “synthetic”? Answer: Synthetic is derived from the word synthesize, referring to a process that involves taking a set of raw materials and making a finished good. Typically, the process includes a series of chemical or manufacturing steps that produce a chemical compound with planned and predictable properties. These processes usually more…

Diesel emissions technologies

According to the EPA, “more than 11 million diesel engines in operation today do not meet EPA’s new clean diesel standards, yet these engines can continue to operate for 20 to 30 years” (www.epa.gov/cleandiesel). Environmental reform is one of the most important issues facing the country today. Smelly fleets The EPA developed the National Clean more…

Tech Trends: Fuel System Technologies

With the fickle availability of refined fuels and the price of crude oil ever on the rise, fuel economy is a concern now more than ever. And as a result, fuel system technologies are undergoing dramatic change. Recently, major vehicle manufacturers are focusing primarily on improving fuel economy through better weight-to-power ratios while reducing exhaust more…
