Oil is cheap, or relatively so compared with the cost of a Defender. I changed at 860 miles and again at 5000 miles. I bought the Defender andI will change every 5k. My dealer will perform the service for 230.00. Well worth it.
How exactly do you folks take the sample when vacuuming the oil? Blackstone instructions say "take a sample from the middle", do you stop and take it from the cylinder, or just at the end of it since it is pretty much mixed up?
suck out the oil
shake the collection vessel
pump out a sample
