After having serious neighbor problems that nearly ended in my death, I would never say a thing about such minor bothers. You never know what's in somebody's head. The issue is escalation. Especially with people who feel entitled. They will double down on stupid, if you annoy them by...

My 2003 Jaguar X-Type gets horrible MPG on regular fuel. It is sensing an insane number of knock events and retarding the ign timing/adding fuel, etc. MPG drops wildly, from 27mpg to 16 or less. If both O2 sensors are good, no leaking injectors, the coolant, air and airflow sensors are...

I end up using wired earbuds for physical activity. Otherwise they fail and also fall out too often. I purchase the Columbia shirts with velcro pockets for my phone. Skull Candy USB-C. I must have 10 pairs of bluetooth earbuds sitting around. Half of which no longer work. Yeah, old school and...

I've run this experiment so many times now, I know what works for me. I change at 1000, 5000 and every multiple of 5000. 25,000, 30,000, 35,000, etc. I use a quality synthetic like Mobil 1 EP and go on my way without worry if I pass the 35000 mile mark a little if I am on a long trip. I...

Just another thought. You could use thermocouples carefully taped and tied on to the oil cooler inlet and outlet. Your setup with thermostat may be bypassing or unable to flow enough through the cooler. You'd see this as cool oil on the cooler outlet. But very hot engine oil in general. Put...

I read this thread with interest. Been there, done that. Absolutely some oils of the very same viscosity will run cooler in road racing applications. Don't let those who don't race or work on race cars tell you otherwise. PAO's were well known for lower temps, even with higher viscosity. There...

In my corporate aviation career working for a billionaire, I had the pleasure of driving many exotic and super fast or ultra luxurious cars. I am a fast car guy, not luxury. However, there comes a point where there is enough power. About 600HP for a RWD car, and about 1000HP for an AWD exotic...

Note: A water softener does not reduce the TDS because it swaps one ion for another. Calcium for sodium as a typical example. Note2: A good RO system that follows a good softener should show zero or very near zero on the TDS meter. Although 15 is generally fine, if mine gets that high, the RO...

Here in Florida, about a year. More if in the garage.

And yet I’m driving a 24year old computerized Jaguar with 236k. I won’t say it is trouble free. But so far the computers still function. The switches in the locks and for lighting/doors have been a real problem. But I get your point. The electrically complex machines do struggle in...

What's interesting is that for most designs, the compromises to empennage shape made do not significantly increase Cd. The transition upwards is gentle enough to prevent flow separation, and maybe more importantly, the empennage contributes a relatively small portion of the aircraft's total...

That's the exact type and style of car I've drawn, over and over while daydreaming in college engineering classes. It is a throwback to the GTP cars of yesterday, with big haunches, low slung body, tight cockpit, updated aerodynamics and styling. I absolutely love it! Really too bad they say it...

I don't think there is any downside to your oil change plan. Your oil is robust enough to not be reliant on the additive package to prevent metal to metal contact. While a good quality 5W-40 should suffice all year round, there is no question a modern 15w40 is more shear resistant, with it's...

Note, it is sometimes worthwhile to use both types of resin, Cation and Anion. Cation resins remove positively charged ions like calcium and magnesium (hardness minerals), while anion resins tackle negatively charged ions like nitrates, sulfates, or organic compounds. Together, they can...

The wording is unfortunate and deliberately misleading. Sure, it may not matter for warranty claims if you are diligent enough with your documentation, but it sure matters in the Carfax/detailed records. The word "maintenance minder" appears to mean the vehicle was indicating it was due or...
