Now I have searched, and I have seen the demo on bobistheoilguy.com. I have searched many other forums and get about 50/50 of people saying good and bad, and some saying that demo on the site isn't really a good test since it's not like actually being in an engine due to tempature differences, etc. Here's my deal, my truck has 49k miles on it and I do run it hard occasionally, meaning some WOT runs. I currently have 5w20 with 1 qt of the standard lucas stabalizer in it. I may not use it next time, Im just having a hard time deciding because of alot of people saying good and bad things. Since I run my truck hard sometimes I just want the best protection for the engine, and to prevent the rings and seals from wearing quickly. I just figured the lucas would give it some more "cushion" to prevent some wear early. I woulden't say I abuse the engine, but It just sees high rpms at times. Do you guys think I should just use the 5w20 synblend oil alone without anything or just keep doing what im doing now. I don't want a full syn oil, because I already did that and I had a leak. Im happy with the motorcraft synblend. Im just having trouble deciding on if I should keep the lucas in there for extra protection. If I didn't ever run the truck hard I wouldn't even worry about it, but since I do im just afraid the 5w20 alone will be too thin and not protect well when it see's high rpms. Any help is appreicated.

Thanks,
Mike

 

as far as lucas products go, I'm not sure, I never tried them so I can't speak much of them. Like you though, I've read and heard both sides of the story.

I'm not a big believer in oil additives, I think there a waste of money if you follow proper OCI's and use good oil and a filter.

Anyway, If you only run your truck hard occasionally, no engine issues etc... I don't see why you need it, yet I don't see why not either. If it were me, I'd just keep sticking with the motorcraft 5w20. Even at high RPM's the 5w20 will hold up well.

Besides with winter coming up, thinner is better. -Mike-

 

i never have run any additives in my oil... i think the best way to protect your engine is to change the oil hot and change it often

 

You don't need the Lucas oil additive. The 5w20 synblend will do just fine alone, probably better, in fact.

If you're concerend about hard driving, just change the oil more frequently (3K or so).

 

I do change every 3k.

 

When I first got my truck (new) I used the synthetic heavy duty stabilizer and it worked well.Stopped using anything except changing oil every 3k.Just last oil change I put in the regular heavy duty stabilizer and You can really notice the difference in the engine performance .I highly recommend it .I think it would be alot safer then the stuff people put thru the booster.

 

Also check out all the testimonials on the Lucas web site.

 

Yeah, Ive seen the comments on the site, and I chose the regular over the syn because Im avoiding synthetics besides the synblend oil which is fine. The regular stabalizer says it can be mixed with regular or synthetic so I use that. As far as the stuff your talking about in the booster, that's seafoam, and it's for something totally different, I think its more for just cleaning carbon out of your engine. The lucas is just an oil stabalizer.

 

Seafoam says it is an oil stabilizer too.

 

you can use seafoam in the oil. it cleans out all the oil galleries and bearings. it works pretty good at cleaning the inside of the engine as well as removing carbon from the top end of the engine.
but i prefer to use "engine restore" in my oil. i find it protects better than anything else. i used lucas in the oil in my 99 kenworth and i never noticed a difference. with engine restore in it i got a bit better mileage( nothing drastic only0.5-1 mpg better) but it made a difference in my oil pressure. it went up by about 5 psi. and when we rebuilt the motor it was nice and clean and noticeably less wear on engine parts than my last rebuild when i was only using lucas.

 

i could of sworn that RESTORE stuff got rid of a tick i had when i added it to the oil change.


the times i dont put it in now, i get a tick, i dont know what the tick is though.
