I like the above as the most realistic answer. I'm running a 45 year old BMW motorcycle on "synthetic" oil and of course it mists a little oil but no more than in did on non synthetic oil. To say using synthetic oils on old vehicles always causes leaks is nonsense not least because most oil...

Is no one going for method B ? I would have thought the donor vehicle is at least risk if it's off.

I don't check the oil because after 18 years of ownership I know it doesn't use enough to need checking. I do check the tyre pressures because I know that the tubes lose air slowly. I know that front loses more than the rear so the front gets checked more often. Thankfully I have shaft drive so...

If you like to read a number of books that have continuity then Asimov novels are worth looking at.

Given oil consumption can occur through loss via the engine breather and the breather gets an easier time when there is more air space in the sump, then for this aspect of oil consumption I believe that oil consumption falls when the oil level in the sump is lower.

Yes the K75 had as balance shaft and was much smoother than the 4 cylinder K100 that didn't Most 3 cylinder engines in cars do have a balancer shaft to smooth out the rocking couple but the Ford Ecoboost 1.0 doesn't. It uses an unbalanced flywheel instead to save the frictional losses of a...

I tried it on some difficult to kill weeds on my block paved driveway and it really works. That's where mines going from now on.

I've driven a few 3 cylinder cars. The Stellantis 1.2 in a Peugeot I thought was an excellent engine and smooth both on the move and at idle. A Volkswagen 1.0 3 cylinder was fine on the move but at idle it was very obviously not as smooth as a 4 and that's something I couldn't live with.

I don't know that there can be a fixed rpm which is damaging to the DMF for all vehicles. Essentially the DMF is working too hard if without it, the vehicle would be perceived to be lugging. So what's lugging ? "Lugging is what we feel when the cyclic variations in the crankshaft rotational...

The reason they use different names for the low viscosity versions of DOT 4 is because there is no official DOT standard for low viscosity fluid. They are all just marketing terms and it’s very confusing that each manufacture thought it appropriate to invent their own name. Look closer and...

75W85 might have been easier to find as it's becoming more common. BMW have come a long way with the motorcycle final drive spec. It started as straight 90W back in the 70's with 80W acceptable in winter. Then 80W90 was permissible year round. I use 75W90 in my 1979 model but next time may use...

One meets the DOT 4 spec and the other doesn't. DOT 4 has a higher boiling point but It's probably of negligible importance. The main reason for choosing DOT 3 over DOT 4 would be 3 is slower to absorb moisture than 4 so it might depend on your intended replacement frequency. If a higher...

The Varta OEM battery in my car lasted 12 years and I'm 10 years in on my motorcycle battery which is a cheap generic AGM/Gel hybrid. One thing that has definitely changed in the last 15 years is the advent of smart alternators which are now designed specifically to not fully charge the battery...

Arcing upon insertion under load is absolutely normal. Reduce load if possible and Insert quickly. Arcing once inserted is not at all normal and needs to be addresses but I can't see well enough from the photos if that has taken place. Every switch from a humble light switch upwards to...

I thought fuel tanks had a nitrogen blanket to minimise the risk of explosions even in the presence of an ignition source. Fuel tanks have exploded in the past (1996 crash of TWA Flight 800, explosion in the center wing fuel tank) which is why inerting systems were introduced.

It's reported that passengers not having their seat belt fastened hit the ceiling and were injured. The report of descending 6000 ft in 3 mins is not an good explanation because a steady 2000ft/min wouldn't have you hitting the ceiling would it ? There must have been a very sudden drop of...

The last set of new Bosch rotors I fitted were coated. Never having used coated rotors before I thought this was going to be positive attribute that kept the rotors rust free on the upswept areas and that it would be designed to quickly wear off on the swept area or perhaps even aid the pads...

Many years ago I saw in the UK Science Museum, both a US space capsule and a Russian space capsule. Big contrast in which looked the best build quality. The Russian capsule looked like it had been made in someones shed.

This is counter intuitive to me too as I have visited this issue in my choice of car. When I bought my current car the annual road tax was based on CO2 emissions with a break point at 150g/Km after which the tax went up by 25%. There was a choice of tyre sizes as shown below and the wider tyre...

That's correct, the one I drove was a dry clutch transmission. The wet clutch is available here but only with the 2.0 litre engine which is mostly the 300 HP GTI model in our market. Good to hear America got a better transmission.
