I just recieved xado revitalizant gel and 10w-40 motor oil for 235k km
After reading many reviews this gel is suppose to increase engine compression reduce fuel consumption and it tested by TÜV

I tought about share this here in case that anyone may need such treatment
has anyone tried it already?
 
I've not tried this particular product, but I do swear by Ametech Engine Restore to cure oil-burning and compression issues. Due to mistreatment by the previous owner, my engine was in need of a rebuild at just 40,000 miles. However, using Restore at every oil change, it's now approaching 80,000 miles and the hydrocarbon emissions are less than 1/3 of the permissible level, so I have every confidence in it as a product.
 
Thanks for the information. I would be interested to know the compression before and after treatment and how the fuel consumption has changed. How bad is your compression?
Nearly all car manufacturers and oil manufacturers say do not use additives but every day is a school day as they say.
 
I test only the 4th cylinder and it reads 13.5 bar I think that is not bad and btw my engine is good but the little problem with oil consumption is slightly high about 300ml per 2000km I will try to do compression test for the rest of cylinders before adding this product
 
If something is worn, piston rings, valve seals, valve seats, gears etc then replace them, putting some sort of gel in there to fill in the gaps is only the mechanical equivalent of slapping a band aid on it.

I've seen lots of people use all these forms of additive over the years only to find that at some point an oil feed to a camshaft or the like gets blocked and you end up with shagged journals.

I would want to test all four wet and dry before making any decision about an additive. Generally a decision to slap on the band aid is a last resort and the motor is so bad that the additve couldn't make things worse.
 
Yes I agree because I've seen lots of useless oil additives reviews but I think this is different please google it then tell me what you think
And second thing I think o do not have parts worn enough to be replaced
 
Whereas I can recommend Ametech hand-on-heart. Before treatment Max to Min on the dipstick was half a tank of fuel, after treatment, depends on driving but about 4 tanks between it going from max to halfway to minimum. I now check and top up every 2 tanks.

The only use for these IMHO is to cover up an issue when you're going to flog the car.

I disagree in my instance, the permanent solution was to have the engine removed, the cylinders re-bored and larger pistons fitted to account for the greater internal diameter. That would have been £2500 of work on a £3000 car at the time. Using a £25 can of Ametech at every 6-month oil change costs a mere £50 a year, and maybe another £50 in oil top-ups. I would have to run the car for 25 years to get a return on my rebuild.

Of course, since it's worth less now, and I'm more confident working on the car myself, a rebuild could be done for a lot less expense, but probably still not worth it for how much longer I'll keep the car.
 
If the car is regularly serviced then at the most you'll only need to replace rings, the only time you need to go the pistons and rebore route is if the bores are scored.

I've done loads of rebuilds where a new set of rings and a quick whizz with a honing tool are all that's needed.

If you're being charged £2.5k for a rebuild on a 4 cylinder Fiat engine then I seriously under charged the guy by about £2k for the rebuild on the 6 cylinder Honda engine I did for his bike a year ago :cry:
 
The bore is slightly scored. This is why I now take full service history with a healthy pinch of salt. I would much rather take a car that's been serviced by an enthusiastic owner than one that has all the right rubber stamps, but a previous owner with not a clue.
 
the gel is just a bandaid

What you owt to be doing if the engine showing signs of age and been worn is to step an oil grade

For example - originally on 10w-40
go to 15w-40, the slightly thicker oil will help with sealing

But a poor seal = lack of oil pressure too
Fix the problem rather then mask it, stepping up the oil is only a temporary fix, as the oil will still get past

ive yet to see a wonder package that puts metal back on worn components

get it bought if you have too much money or little sense


keeps the wheels of industry going


no offence anyone but the emperors new clothes never fitted me after i bought them on a boot sale:mad::mad::mad::mad::mad::mad::mad:


:D
 
I already bought anyway and changed the oil and did compression test
1:12 2:12.5 4:12.5bar or175psi
The third cylinder wasn't reachable for my cheap compression tester and I will have ton test again after 1500 km
 
After about 2500 km I only mesure 2 it is now 12 bar (the sameas before) and 4 11.5 bar (less by 1 bar) but cylinder 4 spark plug was oily I dont know if this could a serious problem
 
oily spark plug is called for concern and needs looking into it, it could be simple as oil leakage from the rocker cover (quite common) or the oil ring on the piston is worn out so some oil might be getting in that way, pull out the plug wipe it down and the rocker cover if theres any oil lurking about, whack it back in give it a good drive about and check it (obviously, waiting for it to cool down again).

neglecting this issue could lead to severe engine troubles (y)

Oil consumption = about 250ml / 1000 miles. That's well with FIAT's acceptable limits. IIRC, anything up to 700ml / 1000 miles is fine, and the figure is higher for Alfas of the same period.
