I've read some about MaxLife and I want to share this article with you:
Valvoline MaxLife passes TÜV Nord test with flying colours
TÜV Nord's review of test data on MaxLife, the only motor oil to be specifically designed for use with older engines, concludes that the product delivers clear benefits
TÜV Nord, one of Europe's leading independent international approvals bodies, has fully endorsed Valvoline's claims about MaxLife, the first motor oil to be specifically designed for use with older engines.
Zwijndrecht, January 2003. Already used by millions of motorists across Europe and the US, MaxLife is claimed by Valvoline to address many of the typical symptoms shown by higher mileage (>100,000 km) engines. In particular, Valvoline claims that the product reduces oil leaks, reduces oxidation and deposits, improves seal condition and has superior wear performance. TÜV Nord's report examined Valvoline's test methodology and data in detail.
To test Valvoline's claim on oil consumption, TÜV Nord reviewed data taken from Valvoline's tests on two older cars from major European car manufacturers using MaxLife and a competitor's oil of the same grade. Each car was tested twice. On all tests, MaxLife reduced consumption, and in one case, improvement was as high as 69%.
On oxidation and deposit performance, TÜV Nord analysed Valvoline's data from an 80-hour test on a 1997 gasoline engine. TÜV Nord confirmed that the deposit data not only showed that MaxLife greatly exceeds the API SJ/CF, ACEA A3/B2 requirement, but that the WPD (Weighted Piston Deposit) rating is 1.45 points higher than the API SL limit and is 0.6 higher than the API SL/CF, ACEA A3/B3 level.
Wear performance, too, was shown to be excellent when using MaxLife. After analysing data from a Sequence IV-A test - a 100 hour cyclical test performed on a 2.4 litre, 4 cylinder gasoline engine - TÜV concluded that "MaxLife ...shows an average wear of only 37.1 um - nearly 80.9 um less wear than the typical API SL oil or API SL/CF, ACEA A3/B3 oil."
Another benefit of MaxLife's unique formulation is its ability to restore seal condition and improve operation. After validating Valvoline's test methodology, TÜV Nord analysed the resulting data from a low-temperature follow-ability test rig to establish the reality behind the claim. Without the additive, the average seal failure temperature is - 17° C. This falls to - 21° C by adding the special additive, which indicates that the seal conditioner additive in MaxLife can indeed improve dynamic seal performance.
