Yes Norman, you are perfectely fine to add the Lucas oil stabilizer as well as using the 5W20 shell oil. No harm will come for doing so.

He has been a ford truck technician for 30 years.

 

This is a ford truck tech with 30 years experience.

 

the ford tech that did my 1st and only dealer oil change on my 5.4 put 5 quarts of oil in. If that tells you anything.
Personally, I'll heed the advice of the engineers that designed the 3v dohc 5.4 and continue using 5W20 without any gunky additives and guess that I'll someday report 300k trouble free miles.

 

Send in a sample of lucas to a lab like Blackstone and get a VOA done. Unless they have changed the formulation in the past 5 years it will come back as pure base oil. The same base oil that is in every conventional engine oil out there except Lucas is thicker. Will it destroy your engine? Doubtful but it is still a huge waste of money unless you are trying to keep an old worn out smoker alive for another 6 months.

 

I do my own oil changes,have done so for about 30 years have used lucas for many years and have never had any problems with any engine i have used it in.Current vehicle has 150k on it,change oil every 5k,no noises or oil consumption just a bit of injector tick which seems to be normal for these engines.

 

Well I think I'm just gonna drain it and fill it back up with 6litres of 5w20

Now with this new ducking issue I have I'm starting to lose my love for this truck

 

Nice joke!

 

U can believe the 20W crap all you want, its for gas mileage. Put in best 5W30 full synthetic and quit worrying. It will also stop the rattle on start up. No matter how much you spend on 5w20 its still junk in a broke in motor ! The Fleet gas mileage thing is about the cold startups and driving for 10 minutes and shutting it off. The truck needs lubrication to be worked as a truck. That is what 5w30 full synthetic offers. Sure if you have 20 below nights 5W20 us going to work well. But if you drive on 120 degree asphalt forget 5w20 and go with 5w30 full synthetic. This is common knowledge for near 70 years. Notice I didn't say 10W40 Full synthetic. I have witnessed so many of those broken front ends of 5.4L motors. that only had synthetic blend 5w20 oils, Blah ! Fleet gas mileage standards are the reason for 5w20 Blended oils.
