My previous is TWS Edge Professional. This latest is from a 3.5k change using 0w-40 (I had to change to replace a failing oil sensor.)
Car: 08, not driven daily, weekends maybe once per month now, aside from exhaust, it's bone stock, esp the air filter, 3.5k represents a year's worth of driving.
The noticeable things during this cycle with 0w-40
- Needed to add oil (this is NOT a bad thing)
- Engine was a tad louder (not always a bad thing)
- Oil temp fluctuations cooled faster (needle moves more, TWS needle rarely moved from 215F or so in the summer)
- Iron and aluminum are higher (slightly, as in line with others using 0w-40)
- Lead is down (again, slightly, my lead values have never been above 3, I have to log into blackstone to find my other 2 reports for TWS)
Suffice to say I went back to TWS Edge Pro since this is a very small difference and in my climate, TWS makes more sense. Maybe for those in freezing, sub-zero climates, it will. For now, looks like I got a good "one".
EDIT: I spoke with my Indy mechanic about the higher iron, his two-word response: "iron camshafts", said he'd rather sacrifice the rod bearings as opposed to "going topside" with head work in the S65.
