APPLICATION
RCI 100 is suitable for use in a wide range of vehicles including passenger cars, light commercials vehicles,
motorcycles, trucks, buses, stationary engines and other equipment.
RCI 100 when mixed with water will help provide improved heat transfer abilities over straight water by reducing
cavitation and eliminating hot spots inside the engine. This can help lower the running temperature of the engine,
preventing damage from overheating whilst the inhibitor pack will prevent rust, corrosion, scaling and oxidation if
maintained at the correct dosage.

This is very hard to find item.
Size: 1 Quart, Style: 6-Pack, Configuration: Euro LX 0W-30
This is one of the lowest VOC oils. Important if your vehicle is GDI. Should help keep valves cleaner.

Went with a 30 weight because of ambient temperatures
Size: 1 Quart, Style: 6-Pack, Configuration: Euro LX 0W-30
Running this in my wife's 2016 Subaru Crosstrek. We live in Arizona and 100+ temps is normal thing. Did a lot of research on this before I decided on running a 30 weight, technically a 40 weight is recommended for our temperature. I noticed that her car was rattling on startup and was worse when it was a hot start. After switching to a 0w-30 I noticed the noise was substantially less. Fuel mileage was not changed she's still averaging 32mpg with her manual transmission vehicle. I've done my research and yes I know about staying with the factory recommended weight but we don't see subzero temperature and we are definitely not seeing the the average 80f summers. 40Fwinters and 105F summers are the norm here. Yes ambient temps effect oil decisions. I also prefer Euro Spec oils over SAE because of Europes extended drain intervals of 10-12k miles. I change every 5k or 6 months.

Fits perfect in my 09 Accord 4-cyl
Style: CA10467
Super easy to install, good quality, fits correctly. What more could you ask? A performance gain, you may ask. Ha. This is a gutless 2.4L 4-banger. No performance to begin with, and no gain after installing this. :-)
