Glider,
On Tuesday, (darn the holiday!!), I will be breaking in my re-redone 1989 FLHTCU with a Screaming Eagle III (top and bottom end - I did it myself, with lots of help from the garage owner and several people in this forum :worthy).
Quick recap - I bought her this April and recently, experience a slight loss in compression in the front cylinder (cold seizing) and opted to take care of the oil leak in the crankcase while doing the top end.
To the point: I still have the pre-teardown oil filter containing 20w50 semi-synthetic oil) in place as well as a small amount of oil contained in the oil tank and oil cooler. I plan to break the new motor in with non-synthetic 10w40 oil. Should I replace the oil filter and remove all the 20w50 as possible or is it okay to mix the two oils during the start up?
I have my route all picked out for the 30-60 break-in, but what about when I first start her in the shop? The garage owner (he will absolutely be there) loves to rev the engines right after he starts them -- getting into the 3-4000 rpm range if not higher, while still on the lift anic. I hate to get so incredibly picky, but this is VERY important to me!! Also, he is insisting all we need to do is add the non-synthetic oil and after driving her around at normal speeds for 500 miles, then changing the filter. What is the max amount of milage after, the 100 or so miles of the 30-60, can/should I go before I change the filter and switch to the semi-synthetic 20w50 again :unsure?
By the way, I live in Arizona :ARIZONA and the oil cooler made an incredible difference in keeping her cool on these hot days!! :yes
Thanks for helping us get back on the road!!:rider
