Well as most of you know I am an Amsoil user as I have have had great success with my vehicles in the past, even after tearing them down after cracked ringlands. I am very happy with the product and I like to run extended drain intervals on my oil for simplicity and cost sake.

I ran OEM oil until the 5K service at which point a switched over to 0w30 signature series oil.

at 14K I swapped just the filter, and took my oil sample and sent it to Blackstone Labs for IOA. I was surprised to find the response was that my engine was still breaking in and that wear metals and silicon content was high in the sample. Metal from mechanical parts and Silcon from sandcasted parts and assembly lubes and sealers from the factory.

Basically Blackstone is saying I should monitor the oil again after 4K miles. But sometime is nagging at me as I had the daler take the oil sample. With the free form OEM oil filter and the sample being taken from the oil filter chamber, I am wondering if the sample is not contaminated from trapped contents being back flushed into the sample potentially.

I changed the oil again and took another sample mid stream to send in, but figured if I had already changed the oil, why bother. I thing I will send it in to get peice of mind, but I thought I would post up on my experience to share that I am not very impressed with the stock Oil filter setup. Seems like a good idea to prevent us from ever using and aftermarket filter and with few benefits.

I will be changning these puppies every 5K looks like. I already bought 10 to keep on hand. Not much to them at all really.

Hey Fig. The F shares the filter cartridge dimensions with most of the other UR V8 engines... Tundra, Land Cruiser, LS cars etc. The filter part number you purchase for the F is sold in foreign markets for some of the diesels... 04152-51010. Toyota was supplying it in their 04152 - 38020 filter kit but superceded to the US made 04152 - YZZA4. There are some aftermarket filters available... Purolator is one.

Do you know the proper way to drain the cartridge housing on the F?

Good info, I knew it shared some of the filter applications, but I had not seen a synthetic media replacement in any of the applications. There are no special instructions on the filter housing drain in the service manual.

So Purolator PN L25702 is what I will check into next. Thanks for the heads up. What is this turbo diesel Landcruiser you speak of?

Picked up the purolator today. Made in india, comes with the drain plug hose (which I have never figured out where to put). Filter media looks the same. just fyi.

^^^^The drain is for oil filters that have a vertical orientation, like my wife's ES, and the trucks that use this filter. Out filters are have a horizontal orientation so the parts with the drain plug are not included in the filter kit specifically designated for the F.

Makes sense
