    HT/HS, lower = slightly better fuel economy BUT

    Quite interesting that discussions of lower HT/HS always center around improved fuel economy, but never mention increased or equal longevity of engines or reduced wear compared to high HT/HS.🤔 Older video:

    Why shorter OCI with non-synthetic?

    I have read several comments where members have stated they do not exceed 3-5k with non-synthetics and was curious why? There are several none synthetics that have a higher TBN then some synthetics and stay in grade, so why change sooner that a non extended drain synthetic?

    Castrol GTX HM SP

    I was wondering how much the SP formula will vary from the SN Plus for Castrol 5w-30? Looks like the SN Plus was pretty stout at almost 9 TBN and 2200 in Ca + Mg I suspect the SP is identical to SN plus? However listed approvals...

    Help selecting Battery charger

    I have been reading the thread of JHZR2 and it seems a few here are fans of Noco or ctek. I am in the market for a new charger and was thinking of a wheeled schumacher. Now I am not sure on what to get. Most of the new chargers all say microprocessor controlled. Is there really that big a...

    Oil Testing

    Was curious as to why the Timken bearing wear test is not used more to test the lubricity of the oils and measuring the wear scar? Wouldn’t this provide some idea of how the oil would protect I know it does not quite simulate exact engine conditions, but it could be a relative comparison...

    TES 295 ATF in a PS calling for DEXIII

    I know in the past the TES-295 carried a DEXIII approval. Does anyone know if the TES295 SPEC changed recently or is the formulation still "compatible or suitable" to use in DEXIII applications? I also plan on using it on a 2012 Silverado PS pump that calls for some GM part#. I have Delvac 1 ATF...

    Thick vs. Thin

    I was poking around Valvolines website and ran across this in the FAQ. “Is it ok to use 5W-30 in a car if the owner's manual calls for 5W-20? Valvoline does not recommend doing this. Using a heavier grade than recommended may cause decrease in fuel economy, higher engine loads and eventually...
