    I don’t feel insulted. BITOG can be great! And, at other times groups of members can be demeaning, insulting and at the same time super sensitive - so if you give it back to them at all you get reported, warned and/or banned. I’m probably going to be warned or banned for this completely true...

    Z-ROD Rust & Corrosion Inhibitors?

    They did come out amazing. $13,000 for the car and both sets of wheels and tires. $12,500 if I can keep the white set. I’m in Roanoke, Virginia. The car has a black label ZF6 transmission too: From Hib Halverson The early ZFs (black label 89-93.5), had an input torque rating of 450 lb/ft, and...

    Z-ROD Rust & Corrosion Inhibitors?

    The bronze wheels are one of our sets of track / autocross wheels, they have 200 tw tires on them. There’s an autocross track at Carlisle and my son and I wanted to drive some laps on it, so we put the bronze wheels on the 89 before heading up to Corvettes at Carlisle. The white wheels have...

    Z-ROD Rust & Corrosion Inhibitors?

    I have three old Corvettes that sometimes are not driven for a month or more at a time, especially during the winter months. I was on the Amsoil sight reading over their oil descriptions and noticed "Z-ROD Synthetic Motor Oil is formulated with a unique blend of rust and corrosion inhibitors...

    My future UOAs that will be meaningful / worth considering will really be my wife's 06 Prius and my son's 05 Prius. Those are our only daily drivers. My 93 Corvette will be autocross raced and see some track days but I doubt it'll see 2,000 total miles annually. I'll do UOAs for the 93 at a...

    I see what you mean - I'm using 15w50 the Corvettes and seeing if 10w40 HM alone works well in the Prius, Limo and Caravan.

    Lucas caused viscosity increases and diluted the additive packages. My Lucas use has also correlated with low UOA indicated wear metals.

    I spend a LOT of time on BITOG in 2004 thru 2007 (my user name was SUNRG). I was hypermileing TDIs, driving a ton, and trying to optimize fuel economy along with low wear. After I sold my TDIs I did UOAs only occasionally for years and didn’t post here or tune in at all. Then I started getting...

    Like 18-19 years ago VW introduced the Pumpe Deuce TDI and it was susceptible to early and accelerated cam wear. The initial VW spec was 505.01 a light 5w40, then the 506.01 spec superseded it which was a 0w30. The promise was that this advanced new light formulation would protect even better...

    Here’s a short video I recorded just before installing the M1 10w40 + Lucas.

    I hope they take aways are: “sometimes, in some applications, under some operating conditions, simply increasing viscosity reduces wear and oil consumption.” And “if increased viscosity is desired, achieving it with a fully formulated oil is probably better and definitely less expensive than...

    well then, since this UOA is an I feel confident the engine is going to be fine. Seriously, I literally paid $200 for this minivan, so every time I turn the key forward and it starts I’m thrilled! When I bought it the oil dipstick was rusted into the dipstick tube making it impossible to...

    Yes. We're not traveling to bike races in this vehicle much any longer and we're not driving it cross country - so the next UOA won't be like these. But I will post it.
