Be prepared Fellas oil formulations as we speak are changing very rapidly due to TGDI.
SN Plus is here.
Formulations with way less calcium & more magnesium is the future.
Less Moly & More Boron & from what I have seen a good shot of Titanium beginning to show up in some brands.
Major Boutique oils are possibly the only future outlet.
Amsoil has even fabricated a special TGDI oil.
Turbo - Direct Injection —>D1G2 oils are the future.
Only time will tell if Ram creates the next generation Hemi (DI).
My reading and understanding is so far only major issues have occurred with the turbo direct injection not so much within your normally aspirated direct injection engines.
Just prepare yourself for some really major formulation changes with oil’s with in the next few years. Valvoline has already started it. (Pic posted below)
Even though M1 has switched their formulations a few years ago with way less calcium and more magnesium evidently they seen the possible issues with the valve deposits within the TGDI engines. Maybe the fix is within the PCV systems themselves?
UnFortunately catch cans are not the most viable solution.
Need to get these TGDI engines out and stretch their legs quite often they say the best solution is a good old Italian tuneup
Will be very interesting to see how long Ram Drags their feet with the DI switch within their 5.7L & 6.4L.
