While most gear becomes bigger and heavier as your child grows, the Romi 2‑in‑1 Travel Convertible Car Seat keeps travel remarkably light. At just over 9 lbs., it’s one of the lightest options on the market, designed to make every transfer—from car to car or plane to destination—feel smooth and effortless. Once you’ve arrived, attach the top tether to the carseat shell to transform it into a convenient hands‑free carrying strap that rests comfortably over your shoulder.

This lightweight car seat is designed with EcoCare fabric, our premium, future-friendly, 100%-recycled fabric made from plastic bottles. The yarn produced is soft, comfortable, and breathable. Romi’s clever design also features ultra-soft, yet durable, PureCosi™ fabric and padding made without added fire retardant treatment, to keep your child comfy and secure wherever your journeys take you. This infant to toddler car seat fits babies and kids rear-facing (5–40 lbs. and 19"–40"), and forward-facing (30–50 lbs. and 34.4"–44").

Actual fit may vary. Not all children will comfortably fit in the car seat for the full weight and height ranges listed. Proudly made in Columbus, Indiana.

Works great never had a problem
Size: 5 Quart, Style: Full Synthetic, Configuration: 0W-40
I've been using this mobile one in my 2005 Mercedes kompressor C230 w203 1.8 engine for about 18 years and never had a problem so I will continue to use it. The price was very good compared to other places but I did have to order one extra quart, I don't know why they don't make this mobile one in a six quart jug.

Great for my hot rod!
Size: 5 Quart, Style: Full Synthetic, Configuration: 0W-40
Perfect oil for my hot rod! Add a bottle of zinc and you get great low temp flow as well as good heat protection. As a 0W it flows quickly for good start up protection and the 40W means I get good protection as temps rise. My car has a flat tappet hydraulic cam so I add a bottle of zinc. Has worked great!

European oil… Japanese engine… zero regrets 🇪🇺➡️🇯🇵
Size: 5 Quart, Style: Full Synthetic, Configuration: 0W-40, Size: 5 Quart, Style: Full Synthetic, Configuration: 0W-40
Yes, I know what the label says. “European Car Formula.” Yes, I put it in a 2002 Subaru WRX bugeye with an EJ257 block and EJ205 heads. And yes—this oil absolutely slaps. This engine is not stock, not delicate, and definitely not living an easy life. It sees spirited driving, boost, and the occasional questionable decision. After switching to Mobil 1 0W-40, cold starts are smoother, oil pressure is rock solid, and the motor just feels happier. No weird noises, no drama, no oil consumption surprises. The viscosity is perfect for a performance Subaru build, especially if you’re running tighter tolerances or want strong protection under heat and load. It’s thick enough when hot, flows great when cold, and inspires confidence every time I turn the key. Is it technically “European”? Sure. Does my Subaru care? Not even a little. If you’re running a built engine, turbo setup, or just want a proven, high-quality oil that punches above its weight, this stuff earns its reputation. My bugeye may not be European, but it’s living its best life on this oil. Would absolutely buy again—passport not required.
