    Transmission fluid lifetime

    Here is a quote from Mazda about their transmission fluid. Then they say suggested service interval at specific time/mileage in the Operator's Manual. I see a lot of car manufacturers with sealed transmissions have the same statement. What does lifetime mean for a Mazda Skyactiv manual...

    Going from a PAO to a Ester base MT oil

    Suppose you have a OEM 75w90 GL-4 oil and go to Red Line MT-90. I understand ester base oil swells gaskets. Now down the road you want to go back to the OEM that is PAO. Will there be issues returning to a PAO?

    GL-4/GL-5 gear oils a compromise?

    Been shopping for an alternative to the OEM 75w-90 GL-4 gear oil for my 2019 Miata MT. Aftermarket gear oil has some GL-4 and GL-5 combo in that weight. Am I better off looking at just the GL-4 75w-90 gear oil?

    Curious if any issues here.

    Suppose you use a jug of oil just for a engine flush. Warm up the oil while still on the jack stands then drain back in the jug. Then install the normal oil you would use. Will that jug of oil be good to use for same purpose next oil change?

    Monitoring Filter Efficiency over time

    Was thinking about this regarding filter efficiency in the real world. As part of UOA reports are particle counts and size.

    Media question

    Synthetic media is preferred due to the size of the fiber. Glass is used but what other material can be or are used for filter material. Everything has an up and a down side and I guess glass does too. Are there options in nano materials for filter media for gas car oil filters?
