I use a compatible Motorcraft filter and the Havoline synthetic that comes in the box. It gets hot. The engine is just fine. You don’t need to fret over fancy oil. It’s a Lexus.
Bought a dealer Sell Pack of 12 Motorcraft filters at Rockauto.
I’ve always used the OEM filter and Kirkland 0W-20 oil on my 2013 Skyactiv because I remember reading on the forums that due to the high compression of the engine the Mazda filter is specialized to handle that. Not sure if it’s true but no problems yet on 7.5k OCI.
6 quarts of Castrol edge full synthetic 5w30 and Motorcraft fl400s
Make sure you get an oil that is dexos gen 2
I WAS using Subscribe and Save for Amazon Full Synthetic 5W-30 and Motorcraft FL-910S Filters, but they keep running out of stock
if you use the Ford/Motor raft FL400S, you can put all 6 qts in. Our engines benefit in some way or another from the bit of extra oil, iirc. Makes it easier than measuring out to get to the 5. whatever the stock filter size is
OEM for the engine oil filter.
I've used the spec Motorcraft filter (820S), and Motorcraft 5w20 synthetic oil EVERY TIME. This truck has been an absolute beast, and dead nuts reliable.
I do use Mazda filter rather than aftermarket.
Motorcraft are good. Mobil1 Filters are very good, and are a great idea if your going to for long OCI's. I've used filters from Baldwin - they got very good reviews on the cut-apart tests - and I have a place where I can order a half dozen at a time for less than what I pay for Frams at Walmart. I am using Motorcraft on my F250
