Battery Mate 2503 IG Isolator - 200 Amp, 3 Bank

The Battery Mate is the ultimate solution for charging several batteries simultaneously and is compatible with any type of alternator/battery charger, in both existing and new systems. As the voltage loss between the alternator and battery is negligible, the Battery Mate performs far better than conventional battery isolators. This ensures fast and complete charging of your batteries without having to make additional adjustments to the alternator.

While battery isolators are conventional diode splitters, the Battery Mate's technology is electronic and includes mosfets (transistors). Its components compensate for variations in voltage and ensure that charging continues at the right voltage level, even with several battery banks. The input side on the Battery Mate is connected to the alternator and/or battery charger, while two batteries are connected to the output side. The Battery Mate is easy to install on a DIN rail (industry standard).The Mastervolt Battery Mate can be used in any application even if the standard alternator need external excitation or voltage sensing. In this case the additional IG contact can be connected.

WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to P65Warnings.ca.gov.

Very Good At Capturing Debris Of All Sizes
I have been using this for my 2015 Acura RDX for several years and each time I replace it, the old filter seems to do the job in capturing big and small debris.

The best option there is
Size: 5 Quart, Style: 3-Pack, Pattern Name: Motor Oil, Configuration: 5W-20
I believe this is the best option available. I have a high-mileage truck (over 200k miles and still running great), but standard 4-6k-mile oil changes were costing me over $100 per service, so I wanted to start doing my own oil changes again. I also didn't want to be crawling under the truck every few months, either. This oil offers 15k-mile protection, which, when coupled with a quality filter, cuts my oil changes to once a year, saving me money on changes and still offering high-quality motor lubrication and protection.

This is good stuff!
Size: 5 Quart, Style: 3-Pack, Pattern Name: Motor Oil, Configuration: 5W-30
I use this oil in all my vehicles. Pennzoil just makes some of the best engine oil on the market. IMHO!
