G’day,
With all the discussion about Dan’s engine I just sent the message in to
Blackstone Labs.
I just installed a rebuilt engine in my GMC Motorhome and I would like to
know when I should take the first oil sample? I have been instructed to
drive the vehicle about 500 miles then change the oil and filter. I was told
that was because a newly rebuilt engine will generate a lot of "stuff"
during the break in process. I would assume that it's not worth it to send
in a sample of the 500 mile oil? After the 500 mile oil and filter change I
will start the normal oil change cycle of 3000 miles and send in a sample
from that change for a base line. Comments please. Thank you, Rob PS - It
might be a good idea to include your response on your FAQ page.
Regards,

G'day,
I received the following response from Blackstone Labs:
Quote:
Rob: Thanks for the e-mail. Changing the oil at 500 miles is a good idea and
that would also be a good point to get a sample. There will be a lot of
excess wear and silicon in that sample, though it will also be the "high
water mark" for wear. Everything should look better after that and if it
doesn't, then it's possible a problem may exist. Also, I'll pass this
e-mail on to Kristin. She's the website guru and we may just add this info
to the FAQ.
Let me know if you have any more questions.
Sincerely,
Ryan Stark
