Default Restore?

Does anyone know the pros and cons of using a product like Restore on a high mileage motor? I have 145,000 miles on a 96 SE and it just seems to lack power. It has ALWAYS had oil changes 3000-4000 miles since new but has always dropped a qt of oil arounf changing time. Pontiac said this was not unusual.........I say my 93 SE never did this. Has anyone used Restore and what benefits came about?

Thanks

I used it on my 94 Suburban. It had 145,000 miles on it, and I FELT it gained power, but there'* no way to know for sure, because I didn't do a compression check. From what I understand, it is supposed to be the only product that actually works, but it, like all band-aids, doesn't last. It'* something you're going to have to do every other oil change or so, because it wears off the cylinder walls over time.

One thing I was always nervous about was the fact that this stuff is designed to fill little scratches and cracks in the cylinder walls. Whaddya think it does to the media inside your oil filter?

Ah....The old "tune up in a can" trick!.... Well like everything else in this world: It'* temporary fix! Nothing beats good old machining & replacing parts!

But I think it has to do with tighter tolerences on the 3800 II and skinnier piston rings, diffrent pistons and the sort....I'd say your ok being that its only one quart per 3000-4000 miles. If it was a quart per 1000miles then I would be a bit worried..My cousins car does the same as yours.....Just use good quality oil and change it 3000 miles out no matter what..... or 3 months... Use oil like mobil, havoline, just good quality.. I dont reccomend QS... Quaker sludge...
Normal for who'* 3800 * II? I do a change every 5000 miles, have 89,000 miles on my B, and don't burn even a pint between changes. Is my engine different? Or is the Restore that I've been using since I got it at 65,000 miles doing it'* job? I also use it in my Cad that has 193,000 miles - no oil loss at all - original engine, no rebuild. That car has been using it since 105,000 miles. Another product that I can recommend. Use it everytime you do your oil, just like the can says.

Default Restore?

Thanks for the info......I would have to admit that this car has been TOTALLY different from the 93 B'ville I had. I have never had a car to use oil between changes untill this one, but since it was new the dealer called it "normal". I do think I can notice a better feel as far as HP is concerned, I'll wait for a while b4 I make up my mind on oil consumption. I'll keep changing it like I normally do and using Penzoil 10w30. That is all it has used for life. Thanks.........
