My wife has a reserve in on a 2023 4Runner should be here shortly. I have a 2022 Tacoma. I put in a SS Stahlbus drain valve at the first oil change in the Taco. It is above a knock off TDR skid plate. Running Havoline RS or DS 0w20 which is super convenient since the taco needs six quart and that is what the box holds.
I want to put a drain valve on the 4Runner which will also be above a skid plate. The Stahlbus works well and but there is also the Femco. Thought I might try a Femco in the 4Runner to see which one I like best over time.
Which brings me to my question, I know all thing being equal SS should be stronger than brass. But is there any other advantage or disadvantage to one over the other. Is one more prone to leak due to the different expansion properties of the metals ... brass or SS valve to a steel (or aluminum) oil pan? How about corrosion due to road salt or other chemicals? Just wondering if the material makes much of a difference.
(Note: Both the Taco and 4Runner will be above skid plates. Also, I have a Fumoto valve on a 2004 Ram CTD that has been on there for 19 years since the first oil change ... and I change the oil once a year and it still looks and works like new. I don't worry about it, but I think the screw on drain valves might be marginally better idea.)
