I agree with this and I will continue using Mobil1 15w-50 and stop using the Lucas. I will never use oil 5W-X unless I own a Honda civic,( and that will never happen) BTW I found out about Lucas from 2 people.
1. A diesel mechaninc working on MB
2. A friend of mine truck driver. He does about 3K miles a week with his Kenworth truck and told me that since he used Lucas on his (BIG MAMA Diesel 2 years ago I think) his truck works at his best. He came down one day a year ago and saw my 78 300D and got one the following week, a beautiful 1980 300CD
, he uses Lucas in all his cars everytime he changes the oil. My experince with Lucas was positive on my 123. I used a quart of oil every 1000 miles, but since my car had almost 400K I decided to add Lucas. I never burned oil since then. The car seemed quieter and not much smoke
but indeed maybe compression wasn't that great either
