Capacity of oil separator increases to 6 ounces, very useful in the truck applications! Review: J&L Oil Separator 3.0 adds another 6 oz of capacity. - Very easy installation of additional 6 oz of capacity to my existing 6 oz J&L oil separator. I did have to move wire harness to the inboard side of mounting bracket, but that was an easy adjustment. The additional insert extension was very good quality and comes with neoprene sealing ring. This increases the capacity to 12 fluid oz., which is necessary to extend the emptying service time. The Ford F-150 eco boost 2011-2016 3.5 engine does use the pcv quite a bit at idle and low speed and the older 2013 engine has direct fuel injection without port injection as newer 2017 and above. The added port injection along with direct injection the gasoline is sprayed at idle and low speed, washing the intake valve cleaner of pcv blow by oil accumulations., so oil carbon build up will cause intake valve problems over a longer period of time and the engine will need to be torn down to clean after 100K miles. This oil separator is a must for a 2013 - 2016 3.5 eco boost engine. 2017 plus years still get some pcv blow by deposits but not as much as 2013 - 2016 however these new models could benefit from the J&L Oil separator 3.0 12 fluid oz capacity. Review: Fits like OEM Equipment. - Works very well and the built is excellent. For those not familiar with these recovery systems, it must be stressed that it requires periodic maintenance to be sure that the unit is checked and emptied periodically. Otherwise, the engine seals can be damaged by the excess back pressure in the oil pan. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07ZHKJJ56 | | Best Sellers Rank | #573,617 in Automotive ( See Top 100 in Automotive ) #264 in Automotive Replacement Fuel & Water Separators | | Brand | Jlt | | Customer Reviews | 4.7 4.7 out of 5 stars (214) | | Date First Available | October 23, 2019 | | Item Weight | 4.6 ounces | | Manufacturer Part Number | EXT-B | | Package Dimensions | 7.91 x 5.28 x 2.83 inches | ## Images ![Co. 3.0 Oil Separator Can Extension EXT-B (Black) - Image 1](https://m.media-amazon.com/images/I/51V8aNo5l1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ J&L Oil Separator 3.0 adds another 6 oz of capacity. *by T***C on November 29, 2023* Very easy installation of additional 6 oz of capacity to my existing 6 oz J&L oil separator.

For those not familiar with these recovery systems, it must be stressed that it requires periodic maintenance to be sure that the unit is checked and emptied periodically. Otherwise, the engine seals can be damaged by the excess back pressure in the oil pan. ### ⭐⭐⭐⭐⭐ It's a "nice-to-have" but worth it IMO *by L***E on April 5, 2023* I've been using the J&L separator for about 2 years now on my '12 F150 FX4 Ecoboost and I can tell you that it works. After each oil change I empty the cup out and it's usually about half to 3/4 full. There have been times where I forget to empty it and it comes really close to overflowing. Saw this and figured it would, at least, give me some piece of mind in case I forget to empty the cup routinely. Doubles the capacity of the OEM cup so now I'm cool if I don't empty the cup after each oil change. Installation is simple so you just need to attach this piece to the original cup and tighten it. I tightened it SUPER tight since there should be no reason to detach it in the future. Then just screw it in normally into the separator and you're done. You should make sure you have the clearance to add this piece in. I installed mine the "normal" way by attaching it to the battery and clearance was kinda close. Still works and fits fine but if you installed your separator somewhere else in your engine bay then you'll need to double check clearance before getting this. All in all though, glad I got this. ## Frequently Bought Together - J&L Oil Separator Co. 3.0 Oil Separator Can Extension EXT-B (Black) - J&L Oil Separator Co.
