Amsoil Bypass Filtration Cost Comparison

Will the bypass filtration system be cost effective to use? Let’s look at the numbers for 30,000 miles:


Standard oil change with Amsoil 15W-40 CJ-4 heavy duty diesel engine oil (part # DME) at 15,000 miles

10 quarts DME retails for $8.55 per quart = $85.55

1 Amsoil EAO-52 full flow filter = 18.85

Total, One Oil Change = 104.40

Total, Two 15,000-mile oil changes = 208.40

Bypass oil change with Amsoil 15W-40 CJ-4 heavy duty engine oil (part # DME) at **30,000 miles

12 quarts DME retails for $8.55 per quart = $102.60

*2 EAO-26 Amsoil full flow filters = 46.40

1 EaBP-100 bypass filter = 40.25

Total: = 189.25


Two 15,000-mile oil changes at $104.40 each = $208.40

Bypass Total: = $189.25

Savings with Bypass System per 30,000 miles: = 19.15

*EAO-26 full flow filters are used on the dual remote bypass system

** Oil drain intervals can be extended with used oil analysis


Obviously, the purpose of this comparison is not to hype the savings but to demonstrate that you can use a bypass system and gain all the benefits for no additional costs and, in fact, save some on the overall cost. Most users of the Amsoil bypass systems extend oil drain intervals using oil analysis to at least 60,000 miles, achieving a significant savings on oil change cost with no loss in oil quality. The kit price from www.thelubepage.com, including the custom bracket, is $375; both the kit ($360) and the bracket ($25) are available separately.

Do you need a bypass filtration system? As I explained, in the Winter 2009 issue of maxxTORQUE, the LMM engines, with the new pollution control systems, are well served by bypass filtration. In fact, all diesel engines will benefit from a good bypass filtration system, but the LMM really needs it.

In the next issue of maxxTORQUE, I will explain oil analysis and post some reports from Jon’s Duramax. By first looking at the ins and outs of oil analysis and then reviewing Jon’s specific oil analysis, we should be able to make sense of what he sends us. I am looking forward to seeing the oil analysis and to sharing this beneficial information with you.
