Long time Schaeffer’s user. Unfortunately Schaeffer’s wouldn’t recommend any of their oils for a 528i. So I looked elsewhere. I used Triax in another machine and was very happy with it, so I switch my BMW over to this. It’s super smooth, very responsive, and exceptionally quiet! I am a believer, and will continue to use Triax in this vehicle.
Only oil I'll buy. Best in class additive package
I had been using a German oil in my 2021 Ram 1500 Ecodiesel that said it was equivalent to the MS12991 spec, but my turbo failed at under 100K. After the new turbo I switched to this oil and use the S7 oil booster. Now have 210K on the engine and still going strong. Fast cold starts and excellent fuel economy.
Been using this oil for all my cars, this particular oil for my 2017 VW Jetta 1.4L SE. keeps the engine running quiet and efficiently here in hot Houston, TX. I’ll be trying out TRIAX Pro Engine Flush prior changing the oil this time.
Been using the Euro LX since new. The Ecodiesel has been running great and no problems whatsoever. Haven't had the oil officially tested, but my engine seems to like it. Don't change what isn't broken. The Euro LX is a good oil at a good price and Triax always delivers! Thanks Triax
mpgs went up 3-4 mpg and ticking is quieter
much quieter operation!
mpgs went way up! was seeing 35-38mpg then jumped to over 45mpg. Customer claims the oil change shops used a compliant oil. The single oil change will pay for itself in fuel savings and hopefully end their dpf failures.
Our shop specializes in European cars. Before TRIAX we never had customers asking what oil we put in the their cars, because they run so well. People were calling and asking about the oil because some of their friends wanted it. Replaced Liqui Moly with TRIAX about 8 months ago. No regrets, excellent products.
Hi, I have bought it for VOLKSWAGEN Tiguan 2009 Engine:CCTA car second time. Oil is very good keeps visconcity on high temperatures with turbocharging engine. Fully recommended !!!
BMW 740 2019 and a Audi RS7 really really like it, no oil consumption, VERY smooth engine and way better testing than the OEM oil they gave me from BMW and Audi. Very awesome oil for European cars, but I guess thats what its for hahaha!
