#1 Fram Ultra (cheapest in the eBay 6 pack, can could be stronger)
#2 Royal Purple (cost higher, full syn & stronger can)
#3 Fleetguard Stratapore & Venturi (superior filtration, but $$$)
#4 Bosch Distance Plus (strongest can, blend media, hard to find, sometimes eats ADBVs)
#5 Mobil 1 (blend media, still somewhat expensive)
#6 Fram TG (blend media, silicone ADBV)
#7 Fram XG (new ones have silicone ADBV, sometimes pleat spacing shaky)
#8 Champ Ecore (decent media, don't push them too far)
#9 Premium Guard & other similar Chinese (lots of media, efficiency not great)
#DEAD LAST Purolator & other tearing Mann & Hummel offerings, which also have nitrile ADBVs that harden fast
#4 is not high efficiency like the OP also asked about.
Thought he said "best construction", which also means can strength to me, when a truck sees a lot of gravel roads & kicks up debris. I had to change my last XG3600 early due to a good sized dent that was starting to rust under the Sure-Grip. Unfortunately the Bosch DP is only 99% @ 40 microns-still better than a Wix XP/NAPA Platinum.
