Classic Gear EP 90 is a high-quality mineral SAE 90 single-grade transmission oil with medium EP additives, specially developed for classic manual transmissions and gearboxes. Due to the demands placed on modern transmission oils, many contemporary – often low-viscosity – oils are less suitable or even harmful for classic transmissions with older materials and tolerances.

To safely lubricate classic, valuable, and often expensive vehicles, Kroon-Oil developed the Classic Oils range: a complete range of lubricants fully tailored for use in classic vehicles. Classic Gear EP 90 is based on high-quality mineral base oils and carefully selected additives, which ensure reliable lubrication, protection, and durability without negative effects on classic components.

Thanks to its SAE 90 viscosity, this oil provides a strong lubricating film at operating temperature, ideal for transmissions requiring a slightly thicker GL-4 oil.

Application

Classic Gear EP 90 is suitable for:

  • Classic manual transmissions

  • Gearboxes requiring an SAE 90 single-grade transmission oil

  • Applications requiring a medium EP-doped oil according to API GL-4

  • Classic vehicles with lightly to moderately loaded gears

Not suitable for hypoid differentials or applications requiring a GL-5 oil.

Benefits

  • Excellent lubricating properties

  • Reliable EP protection for classic transmissions

  • Good corrosion protection

  • Excellent anti-foaming properties

  • Fully compatible with classic seals and rubbers

  • Historically correct solution for SAE 90 GL-4 applications

Quick and easy to install
This review is for the INFISTAR AC85111 Cabin Air Filter. To be honest, when I saw this product I was a bit perplexed as to whether our car (Honda Odyssey) even had one! I have never replaced a cabin air filter on any car before. The mechanics might have done so during regular service, but I was not aware of it and had to do an internet search to find out where it would even be installed. Just because of my ignorance, I decided to get it and educate myself. My car actually DID have one and installation would have been a quick and easy job if I remembered to take all the heavy stuff (manuals, etc.) out of the glove box. Because I did not do it, it unhooked it on the right and I had quite a bit of trouble realigning it. If it hadn't been for that, installation would have only take a couple of minutes as it was a breeze. The new filter looks like a good quality product and will last a while. Jury is still out for me on the color though. The old filter was white, so it was easy to see the dirt it trapped. This new filter is almost dirt color which would make it harder to see how dirty it is. However, at such an affordable price, I can replace it as often as I want. I asked my mechanic about it and he said he only replaces cabin air filters if the customer requests it or if he notices a funny odor in the car.

Effective Cabin Air Filter – Fresh and Clean Air for My Car
I recently replaced my car’s cabin air filter with the AC85111 activated carbon filter, and I’ve noticed a clear improvement in air quality inside the vehicle. It helps keep the cabin air fresh, especially during daily commutes and long drives. The activated carbon layer does a good job of reducing dust, odors, and outside pollution, making the driving experience more comfortable. I also noticed less smell from traffic fumes and general road dust entering the car. The fit was perfect for my Honda Pilot, and installation was simple without needing any special tools. It is compatible with several Honda and Acura models, which makes it a reliable replacement option. The material feels well-made and sturdy enough for regular use, ensuring consistent airflow while filtering out impurities effectively. Considering its performance and durability, it also offers good value for money. Overall, this is a practical, easy-to-install, and reliable cabin air filter that helps maintain cleaner and fresher air inside the car.

Good fit for our Honda Accord, quality filter
This was the perfect fit for my daughter's Honda Accord. It's a solid, budget‑friendly upgrade that fits perfectly. It only took a few minutes to install. The pleated material feels sturdy, and the activated carbon layer helps cut down on odors and everyday cabin dust.

No more funky smell!
Have had a funky smell for a while in my car. Air fresheners just couldn't quite cover it up. I pulled the old filter out which was reallll caked up with stuff and got the new one in. Not only is the funky smell finally gone, but the HVAC is a lot quieter when on full blast, and it blows the air harder. It fit great, installation was easy, and having the smell gone makes it worth absolutely every penny.
