For gas Euro cars, Valvoline 5W-40 wins; for hard‑working diesels, Mobil 1 5W-40 leads.
I live in the US, near Denver, where winter mornings can hit single digits and summer climbs fast. I wrote this valvoline vs mobil 1 review to help you pick the right 5W-40 for turbo engines, daily commuting, towing, or high‑mileage rigs. If you want OEM Euro approvals for gasoline turbo cars, valvoline vs mobil 1 leans Valvoline. If you haul, idle, or run a diesel pickup, valvoline vs mobil 1 tilts Mobil 1. I’ll keep it simple, based on real use and verified specs.

Is Mobil 1 Turbo Diesel Truck Full Synthetic Motor Oil 5W-40 Good?
Yes. It’s great for diesel trucks, vans, and hard‑use applications. It also works for many gasoline engines that allow 5W‑40 and API SN.
I run it in a neighbor’s 6.7L diesel that tows a camper up I‑70. Oil pressure stays steady, and consumption is near zero between 7,500‑mile changes.
I also used it in an older 4.0L gas SUV during a hot Colorado summer. The idle felt smoother, and lifter tick disappeared within a week.
mobil 1″>What Makes It Stand Out / Key Features
- API CK‑4 diesel rating; backward compatible with CJ‑4/CI‑4+
- API SN gasoline rating for many non‑DPF gas engines
- Robust detergent and dispersant system for soot control
- Strong high‑temperature stability for towing and long idling
- Excellent cold‑start flow for a 5W grade
- Shear‑stable 40‑weight for sustained highway loads
- Good TBN retention for extended intervals where allowed
What I Like
- Handles heavy towing and high EGTs without thinning
- Reduces valvetrain noise in older engines
- Low volatility helps minimize top‑offs
- Reliable in both summer heat and winter starts
- Dual‑rating flexibility for mixed fleets
What Could Be Better
- Not tailored to European gasoline OEM approvals
- Phosphorus levels may not suit some modern GPF-equipped gas cars
- Heavier feel can trim fuel economy in small gas engines
- Overkill for short‑trip city driving in mild climates
- Availability can fluctuate in gallon format
My Recommendation
If you own a diesel pickup, van, or SUV, this is a top pick. For valvoline vs mobil 1 in heavy‑duty use, Mobil 1 gets my nod for durability and soot control at a solid value.
Is Valvoline European Vehicle Full Synthetic 5W-40 Good?
Yes. It’s ideal for European gasoline engines and many turbocharged direct‑injection cars that call for ACEA A3/B4 or specific OEM approvals.
I’ve used it in a VW 2.0T that’s picky about oil. Warm‑up was smooth, and turbo spool felt crisp.
In a BMW inline‑six, oil consumption dropped, and the engine stayed quiet up high in the Rockies.
What Makes It Stand Out / Key Features
- ACEA A3/B4 with high HTHS for strong film strength
- Common Euro approvals such as VW 502 00/505 00
- Often meets MB 229.5/229.3 and BMW LL‑01 needs
- Porsche A40 compatibility for high‑temp stability
- Excellent deposit control for turbochargers
- Good protection against LSPI in many DI engines
- Optimized volatility to limit oil burn
What I Like
- OEM approvals make it easy to match manuals
- Stable viscosity keeps engines quiet at high rpm
- Great for spirited driving and mountain grades
- Helps reduce oil consumption in older Euro motors
- Consistent availability in 5‑quart jugs
What Could Be Better
- Not designed for diesel DPF/CK‑4 duty cycles
- May be too thick for tiny turbo 0W‑XX factory specs
- Fewer diesel approvals than Mobil 1 counterpart
- Price can be higher than generic synthetics
- Not a fit where low‑SAPs C3/C5 is required
My Recommendation
For valvoline vs mobil 1 in gasoline Euro cars, choose Valvoline. It aligns with European specs, making warranty compliance simple and protection excellent.
