AI Thread Summary
Honda recommends 0W-20 engine oil for its vehicles, including the Civic, primarily to meet fuel economy standards. While some believe 5W-20 could suffice, especially in moderate climates, using 0W-20 is advised for optimal performance and warranty compliance. The higher cost of 0W-20 is attributed to the superior quality of its base stocks. It's also emphasized that modern vehicles do not require oil changes every 3 months or 3,000 miles, contrary to outdated recommendations. Adhering to the manufacturer's guidelines ensures better engine health and longevity.

My new Civic recommends 0w 20, however it is a bit more expensive, especially if done at a dealership. Is there much difference between 0w 20 and 5w 20? I heard the only reason Honda uses 0w 20 is to meet the MPG guidelines.

In reality you'll be fine with 5W-20. Unless you live in a very cold place or do a lot of short journeys. You really are unlikely to see a difference.

If you are still in a warranty period, just go with the manual.
 
The reason the 0W20 is more expensive is that the base stocks it's made out of are of a substantially higher quality. Use the 0W20 and do NOT pay attention to anyone telling you to use the 3 month, 3,000 mile oil change interval- it's bunk on any car built after 1996.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...

Thread 'Calculate minimum RPM to self-balance a CMG on two legs'

Thread 'Calculate minimum RPM to self-balance a CMG on two legs'

Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...
