You should have added the EPR to a fully warm engine. Not cold.Sorry, didn't have time to do a compression check.
Ran the EPR cleaner today. Added to cold sump of old oil, warmup took about 12 minutes. Ran at 1200rpm for 10min exactly. Gave it a nice long time to drain. Changed filter and filled back up with Rotella T5 15W-40.
When idling after the 10min run there was noticeable but light white smoke from the tailpipe. It also deposited a little bit of crud on the ground.
I'll be monitoring the consumption much more closely at this point.
Fortunately I also found 6 jugs of Havoline 5W-30 or something at Walmart today for $11 a jug so if I have to burn through some more for a while it won't be so pricey
The chemicals need heat to clean the internals properly.
