What is urea Duramax?

The urea-based solution (32.5 percent industrial urea and 67.5 percent deionized water) is held in a 5.3-gallon storage tank and injected as a fine mist into the Duramax’s hot exhaust gases.

What are common problems with LLY Duramax?

The most common issues LLY owners encounter include decreased fuel mileage, overheating and poor turbo response. These symptoms result from the inlet mouthpiece of the Garrett turbocharger having to fit into a smaller engine space.

Is urea a urine?

Urea (also known as carbamide) is a waste product of many living organisms, and is the major organic component of human urine. This is because it is at the end of chain of reactions which break down the amino acids that make up proteins.

What does urea mean?

From a strictly chemical disposition DEF is a mixture of 67.5% deionized water and 32.5% urea. Urea is a compound in Nitrogen that turns to ammonia when heated and is used in a variety of industries. Urea is technically derived from a byproduct of urine but for mass production purposes it is synthetically made.

What’s better LLY or LB7?

Between the 3 LB7s I have a work and my LLY, the LB7 seems to be more ‘sluggish’, a bit less power and louder, BUT seem to be more of a consistant increase in power through the RPMs. My LLY, is much quieter and smoother. The power is dormant right off idle until the turbo spools, then it takes off like a rocket.

Why is LBZ better than lly?

Torque increased as well, going from 605 pound-feet with the LLY to 650 with the LBZ. The LBZ employed a thicker engine block casting, meatier connecting rods, and a higher pressure common-rail fuel system. This gave it more power and reliability versus any other Duramax to that point.

Can I pee in DEF tank?

The urea found in urine is not in the proper concentration needed for DEF, nor is it of a sufficient level of purity, in either urea or water. The bottom line, to spell it out just one more time… urine and DEF = Never. DON’T PEE IN YOUR DEF TANK!

Can you pee in the DEF tank?

Please do not urinate in your DEF tank, the SCR system will be damaged and it will cost thousands of dollars to repair.

What does LLY mean for Duramax?

LLY doesnt stand for anything specific, its just the RPO (regular production order) code that means “Duramax diesel engine”.

What’s better LB7 or lly?

LB7 gets way better fuel economy, runs cooler. I do like the automatic high idle on the LLY(with the auto start), beats walking out in the cold and flipping a switch.
