turbominicooper Posted January 13, 2016 Posted January 13, 2016 ive got some 1040 semi synthetic oil kicking about, is this ok to run new rings and bearings in etc? Quote
funny onion Posted January 13, 2016 Posted January 13, 2016 Ran my overhauled engine in on 1040 semi synthetic. Fired it up, let it run to temp, dropped the oil and changed the filter, drove it for 500 miles, changed oil and filter, then drove it for 1000 miles and did the same been fine for 3 years now Quote
turbominicooper Posted January 13, 2016 Author Posted January 13, 2016 happy days cause got 20L of the stuff for £40. is it worth using the lucas oil stabiliser at any point when running in? Quote
funny onion Posted January 13, 2016 Posted January 13, 2016 I wouldn't use additives or anything... just the oil and a magnetic sump plug Quote
H_D Posted January 13, 2016 Posted January 13, 2016 you really want to risk running in fresh rings with normal oil? good luck to you sir.I would never recommend that, there is a reason why you should always use running in/mineral oil for these circumstances. Quote
Ep82gi Posted January 13, 2016 Posted January 13, 2016 we always run our engines in on toyota 10w40 semi synth never once had a problem. Quote
Whitenoize Posted January 13, 2016 Posted January 13, 2016 (edited) They are old engines they are ment to be run on semi if it's a standard engine id run a good semi if it's forged then fully Edited January 13, 2016 by Whitenoize Quote
