Heres a Subaru with 202k on the clock. Rings in spec, bearings JUST showing copper,still has the hatchmarks on the clyder walls....Do you think your wear will be similar on your Rover at 200,000 Miles? Bet not.
Subaru teardown
Why do you think that is? |
You continue to show your ignorance. The tolerances specified for a motor tell you that it is within serviceable limits, NOT that it hasn't worn. Do you think that one day its not worn and the next day it is. You can't be serious.
I have also seen many Rover V8s with the hone marks still visible after 200,000kms. You can often rebuild them without the need to re-bore.
Bearings showing copper are worn well past tolerances. They are stuffed!

Find me an oil that I can use that will mean that my motor will last forever and I will use it. Again, you can't be serious with such comments.

If you talking like oil for like oil, that is, say a Mobil non-synth 10-30 and a 15-40, it means that at the higher temp the 40 will be thicker and has a higher shear factor.

Because I use an oil that of a higher standard that what was available at the time the car was manufactured. The oil I use can take higher temperatures. So I can still drive it with the oil temp gauge up near the "Max" point. Again, I stated that the water temp is fine. It is just oil under stress heats up.

Where have I said that my motor is worn out. When I replaced my last motor, all the bearings were in near perfect condition. But you seem to have this fixation that a motor will not wear out if you use the right oil. It just shows that you live on a different planet.

You continue to show that you just start typing and don't read. I clearly stated that I use a 15w/60 oil. Can you actually get it through your head that oils have developed well past oils with a very narrow viscosity range.

I don't need to. Your comments are so out there, eg a motor never wearing out, that everyone knows your wrong.
