When it comes to synthetic oil, there are a lot of options available on the market. We feel that, in the huge cloudy malaise that is the oil aisle, it’s important to provide some clear options that have recently reached across the pond from a company that is working on reinventing what retail oil can do. With four distinct product lines, BIZOL (pronounced Bye-zol) is coming to the US for the first time from Germany to provide outstanding quality at a price point that puts it head to head with the industry’s best.
Now a lot of you are probably thinking, oh another oil to mix into the endless sea of 1l and 5l bottles available, but BIZOL is special. Think of it as kind of a “craft oil”, painstakingly designed to be exactly what your engine wants. If you know a lot about oil (like enough to discuss the appropriateness of Sulfated Ash with your buddies at a bar on a Friday night) then hold out for the Technical Post a little later. [edit, this is now live, here: http://www.eeuroparts.com/blog/6721/bizol-the-technical-post/] For now, the only thing you need to know is that American “synthetic” oil is not required to actually be FULLY synthetic to wear the label. It can even be mixed with plain dino oil and as long as the percentage is low enough, it doesn’t have to be called semi-synth. In Europe synthetic oil must be 100% synthetic group III or IV, and BIZOL is exactly that. You may remember back in the day when “German Castrol” or “GC” was all the rage because it was the only actual synthetic oil carried in the major parts chains.
BIZOL is 100% made in Germany using nice uniform sized Group III and Group IV synthetic oil molecules.
When trimmed down, it’s important to know that unlike the other major oil companies, the concept of BIZOL was originally thought up by a guy that wanted to do things a little differently. No deception on the percentage of group 3 synthetic base stocks are actually in it, no complicated deals with manufacturers to make money off OEM contracts. Just starting off with the best quality (and most expensive) North Sea crude oil, refining it down and separating it into pure Group III hydrocracked synthetic base stocks and..
I said I would put the separate blog posts. Be ready for graphs and charts about viscosity indexes, potassium hydroxide TBNs, and oxidative thickening. Oil is complicated.
Getting down the actual product lines, we have four new lines of oil, as well as a few additives. When picking an oil for your European car, it’s important to know your specifications. For instance, Mercedes and VW have some pretty specific specs to which an oil must conform for them to consider it good enough for their engines. BMW is extremely stringent about their Long Life designated oil, because of how much demand they place on oil with their direct injection turbocharged, VERY tight tolerance engines.
Your user manual will list the specs your oil must conform to. My SAAB 9-5 lists the specs as 5w30, 0w30, 5w40 that conforms to ACEA A3/B3, or API SJ or higher. These are pretty basic specs so I can basically pick and choose which I like more. However, if your BMW specifically calls for LL-04, then you must use an oil that conforms to that or you can technically void your warranty. We will soon have exacting specifications for all the cars we support to take the guesswork out of the process, and get you the best oil without spending too much money.
For now, lets focus on the four main oil product lines, and what main specifications they cover:
This is a modern low-friction engine oil best suited for all year use and not specifically designed to fit perfectly into any one category, made primarily of Group III base stocks. It is especially recommended for gasoline engines with three way cats and modern diesel engines with particulate filters. This is their most successful oil in Europe, where most normal family and economy cars are running on high efficiency small displacement diesel and gas engines, generally for shorter trips in a variety of weather conditions. This was just recently approved by Mercedes Benz for their stringent 229.52 oil spec. The main specifications BIZOL Allround 5W30 carries are:
VW 502 00/505 00/ 01
Mercedes Benz 229.51/229.52
Technology is another Group III full synthetic oil, using some of the freshest blends of additives, which is really what makes a modern oil perform. It’s a little more expensive, but does conform to the most recent and stringent demands of VW’s new direct injection turbocharged engines, which have very tight tolerances and small, high pressure moving parts. Here are the specifications for 5W30 Technology.
VW 504 00/ 507 00
Mercedes Benz 229.51
I wanted to note that the 10W60 Technology is a Group IV Synthetic, which is the highest current tier of synthetic oil processes.
BIZOL Protect, like the allround, is a great choice for a huge variety of gasoline and diesel engines. The Protect is best suited for higher mileage cars, and cars using older technology that don’t see the extreme demands placed on a modern engine with high pressure fuel pumps, variable timing, etc. The additives in the Protect oils specifically focus on reduced friction and wear, prolonging the life of an engine that still has a lot of life left in it. It is just fine for engines with or without intercooled exhaust gas turbochargers. The 0w40 is their other Group IV synthetic, and is what I’ll be using in my 170k SAAB 9-5 mentioned above. Here are the manufacturer specifications for the BIZOL Protect 5w40:
VW 502 00/505 00
Mercedes Benz 229.1/229.3
The BIZOL Green has a pretty specific purpose. Unlike the Technology, Allround, and Protect, which are great oils for all normal types of driving, the Green is specially made for drivers that find themselves commonly trapped in the confines of city traffic. Driving downtown is one of the harshest environments in which an engine can be placed. Generally working without much cool air entering the intake and cooling system, and including extended periods of both idling and high throttle, most oils cannot survive the entire manufacturer lifespan in this environment.
Even if your manual specifies a 10k mile oil change interval, don’t be confident that in this harsh environment the oil in your engine will make it all the way to 10k miles. That’s where Green comes in. With excellent binding properties, reduced oil dilution, and enhanced cleaning additives, Green will allow your oil to live out the full change interval in the harshest traffic situations. Here are the specifications for the 5w30
VW: 50200 and 50500
MB: 229.3 and 229.5
If you still want to know more about the specifics, stay tuned as we will be getting a complete suite of spider graphs and oil tests back from Blackstone Labs, but what we have seen so far places BIZOL above all the rest. We are impressed, and that’s pretty difficult seeing how many hours of our day, every day, we spend thinking about things like this. We are currently pouring BIZOL into both of our race engines as we prepare for the new season, kicking off VERY shortly!
