What's your preference: Lucas Oil, Restore Engine treatment, OR Rislone?

My 97 Chevy Express conversion van has 125k miles, tows my pop up camper and just thought I'd look into using something extra as it's getting up there in miles ( I might also have a slight ticking that might be a lifter problem starting). Which do you prefer for older engine maintenance?

 

I used to run that Lucas fuel additive in my 89 every other tank, I think it made a difference. In my wifes car I put Lucas through her Eclipse and didn't tell her, she asked what I did to her car cause she said it ran better.

 

I know that the dealerships are now endorsing oil additives but I think I would stick with regular oil changes and use the high mileage oils that most likely have the additives in them....
thou in my 97 Tahoe with the 5.7 I just used Mobil1 synthetic the whole time I owned it and never had any engine issues but only got to about 130k before I sold it...

 

Original Poster here. I use the Lucas fuel additive and can really tell the difference when I don't use it. However, this time I was asking about an oil additive like Lucas Oil Stabilizer. Thanks for the re-afirmation on the lucas gas treatment though!

 

I never used fuel additives in my 97 but have been regular about using Techron in my 07 Tahoe about every 7k miles and also use the top tier fuels ( Shell, Chevron )

 

Interesting tidbit.....

IMO, this is dangerous ground.

I've had some problems with engines which were running fine, by using "additives" which promised a lot. I could never absolutely prove the additives specifically were at fault. I never saw the promised "increase" in MPG.

My experience has shown there is no substitute for regular oil and vehicle maintenance.

 

I think that pretty much sums it up

 

DONT USE RISLONE I USED IT ON MY 2000 MUSTANG AND BROKE A VALVE SPRING CROSSING THE ARKANSAS RIVER DURING RUSH HOUR TRAFFIC ON I30. Damn lucky to still be alive too.

 

I need to update the Synthetic Oil test post made, lo these few years ago. There is now mountainous amounts of empiric evidence, of the obvious benefits of
synthetic oil, and the price has dropped, making regular oil changes, using synthetic oil, a no-brainer. Recent life developments have reduced my driving habits
to far less mileage than before, which allows me to get away with annual oil changes. (2 vehicles, less than 25K mileage per year total, etc) While I use Mobil1,
and it's a popular leader in the field, any properly API rated synthetic works fine.

As to that engine tick, my experience, at least with Chevy V8s, points to a cracked exhaust manifold or leaking manifold gasket.
