oil filter: K&M vs OEM?
#21
I beg to differ. AMSOIL does not disclose the composition of their base stock for regular or synthetic oil. Pennzoil clearly states that it is 100% synthetic made from natural gas. That is why I use Pennzoil and not AMSOIL. I bet it's because it would be very bad PR for them to disclose they make their synthetic product from a crude oil distillate base stock. If you want a full synthetic that meets European SAPS standards, Pennzoil makes that as well.

Amsoil is the leader on synthetic oil. They follow the European definition of 100% pure synthetic while USA "full" synthetic is not really 100%. Do you buy from a local Amsoil dealer (they only sell through independents) or order from their website?
They also make oil filters for some vehicles. To get their opinion on filtration, google "amsoil oil filter micron rating".
Here is a summary of an SAE study:

One known risk in changing oil filters from the OEM recommendation is the pressure rating on the bypass valve may be significantly different. If it's a lot higher, the oil may not flow (bypass) on startup when the engine is cold.
But this concern is for canister style filters where the bypass valve is built into the housing of the screw-on filter. For the cartridge style filter on our LR2's, the bypass valve is probably in the engine and is fixed to spec.

I purchase Amsoil through their website preferred member program. Being using their gas and gear oils for approx 2 decades first in a V6 marine outboard/lower unit. Was so impressed with their marine products, I now use Amsoil in everything with an engine/tranny. I used their extended drain filters as well but they don't make one for my LR2/FL2 model...
They have tremendous brand loyalty from customers who keep them in business despite the obstacles in buying locally. As flybd5 noted, they are not transparent about their inputs which would make anyone suspicious. But in all the oil comparison tests I've seen, they rank near the top if not #1.

But the other concern is if it bypasses at too low a pressure, sending unfiltered oil to the motor under some conditions.
Yes. The only considerations for us are flow, durability, and micron rating. Any reputable filter should be good for the first two, read the specs for the last.

Mostly run K&N oil filters (for good flow at high rpms while towing).
I tried several oil mag oil plugs over the years, but all had too wide of a flange, found this one on ebay last summer, it fits fine...

That not how MoS2 works. I discussed this at length with the regional manager. You add the FULL oil capacity of the engine and then add the MoS2, because it is an additive and not a substitute. For the LR2 it's eight full liters of oil and 400ml of MoS2 (50 ml per liter of oil). The MoS2 will not remain in suspension in the oil, most of it attaches to the internal metal surfaces of the engine.

I haven’t made the jump to MoS2 yet… but coming from an aircraft mechanic…
So I’ve been thinking about it.
I do change my oil more frequently then described in the Service Manual at about 5000 kms. But have been sticking to the oem filter and the manufacturer’s recommendation for synthetic. Ditto for the Jag.
And I do use magnetic plugs. Of course the ‘fur’ in the diff has lot to do with the fact there isn’t a filter there. Thus emphasizing the need for suitable filters. Don’t get me going on my opinions about the Haldex… clearly not manufactured with longevity in mind.
And finally, returning to the title: yes k&n and amsoil are the greatest…. at least according to their own marketing material. And their own “independent” sponsored tests.
Cheers!
