Performance Profile
- Far exceeds: the requirements of:
- API: SL, CF
- ACEA: A3 / B4
Description
Competition fully synthetic engine oil. Formulated with 100% synthetic base fluids, including a synergistic blend of three esters combined with the latest additive technology for maximum performance.
Application
Use for competition or modified engines where maximum power release is the preferred criteria. Formulated for high revving engines used in circuit racing or for larger engines for short duration i.e. hill climbs and sprints.
User Benefits
- Fully synthetic oils provide many outstanding performance benefits over conventional mineral oil
- By utilising both polyalphaolefins (PAO) and ester synthetics specially selected to minimise the amount of polymer used, the lubricant film provided is more resistant to 'shear' and viscosity loss in high stress areas
- Load carrying capacity many times that of mineral oil. High film strength for ultimate protection. Outstanding cold flow properties for reduced wear at start up. Excellent thermal stability and oxidation resistance. Suitable for operating at 125°C with peak temperatures up to 150oC.
- Provides the optimum balance between hydrodynamic and boundary lubrication and the power absorbed through pumping losses to ensure maximum power release

Wish I Had Used This Sooner – Stop Debating and Just Buy It!
Size: Powder Poli Ox - Pack of 6
Wish I Had Used This Sooner – Stop Debating and Just Buy It!
After a lot of debate, extensive research, and way too many hours spent using other products trying to restore and protect my RV's fiberglass that never fully delivered the results I was after, I finally tried the Poli Glow Deluxe Kit—and I am extremely happy I did. My only regret is not using it sooner instead of letting other people's opinions talk me out of it.
The 6-in-1 complete kit is the right way to tackle fiberglass restoration from start to finish—eliminating oxidation, restoring the shine, and then protecting it long term all in one comprehensive system. The difference in how my RV looks after going through the full Poli Glow process is genuinely impressive and far beyond what any single product or traditional buffing method I tried before could deliver. The oxidation came off cleanly, the restored shine is deep and glossy, and the long-lasting protection gives real peace of mind knowing the fiberglass is shielded from UV damage and the elements going forward—especially important in the brutal Las Vegas sun.
For anyone who has been going back and forth on whether to invest in the full Poli Glow Deluxe Kit—stop debating, stop listening to everyone else's opinion, and just do it. The complete system delivers complete results, and I won't be using anything else on my RV going forward. Highest possible recommendation.

Great stuff.
Size: Powder Poli Ox - Pack of 6, Size: Powder Poli Ox - Pack of 6
My RV had moderate oxidation. I tried several polishes and waxes. Nothing worked well to make it shine out lasted long. I applied poly glow a week ago. It is easy to apply and made my RV shine like new. So far I love Poly glow and if it lasts anywhere a long as they say, I will continue to use it.

It Works!!!!!
Size: Powder Poli Ox - Pack of 6
We have only completed the first two steps it Poly Glo set we purchased and has it ever made a difference in the look of our hauler/trailer! The dull oxidize black color is somewhat shiny. Cant wait to put the final two steps on it! A little elbow grease and work did wonders! We will share a photo once the procedure is complete!

Could be good
Size: Powder Poli Ox - Pack of 6
I cleaned my RV very thorough from top to bottom before even starting the process with the Poli Glow system. Here's what I learned despite videos and lots of reading reviews.
1. Must be very clean and clear of anything you dont want to stick and show on your final outcome.
2. It takes more coats than you think it would (after 3 coats) it was still really streaky and I was starting to regret using Poli Glow. I ended around 7-8 coats and my rig had no major oxidation at all.
3. As one reviewer said, use a clean microfiber cloth v the applicator that comes with it, I found much better results with no lines.
4. Dont go to heavy on the coating, the instructions say this, but I went super light and it can be very easy to get lines with heavier application.
5. Dont look at your work after 3 coats, you will feel deflated, just keep going for at least 6 coats and then look at your work.
6. Only do small areas and look out for drips and lines, you need to get them out right away.
7. I did not use the Poli Ox, I was able to get any oxidation out with just the Poli Prep
8. Going up and down a ladder for hours sucks!
9. I hope it will come off in the next couple of years when I plan to replace the decals. Honestly, thats my biggest fear is how hard it will be to remove when the time comes.
10. After a scary start, I will say it did turn out pretty nice, was it easy, nope, would I do it again? Not sure, I need some time for my back to heal up!
If you do choose Poli Glow know there are other options that maybe a better way to go such as wet sanding etc. Poli Glow is pretty good, but it can be pretty bad also if the surface is not cleaned and the Poli Glow applied correctly.
