Maybe Valvoline comes to your house and changes the oil for you.
Yikes - 40.00 has been topped.

Pardon the ignorant question, but how does any motor oil reduce LSPI? Seems like that would require fuel, or a tune.
This might be a good place to start...also plenty of threads on here.
In short, seems like trace amounts of oil on cylinder walls can trigger destructive preignition in direct injection turbo engines during low RPM, high load conditions.

Greatest post here. DI has cause so much heartache to reverse engineer fixes for all the side effects. Imagine how much money the automotive industry has spent doing R&D to combat the issues of DI all for minuscule MPG increases.
On a side note, given that standard Valvoline "Advanced" full synthetic meeds D1G2, I'm not sure what the market position on this oil is, especially since it is $18 per 5 quart jug more expensive.

In 1975, Mobil 1 was $4.00 a quart and was only sold at Mobil gas stations. And since someone mentioned sales tax... add another 4% (the sales tax rate back then).
Adjusting for inflation, $4.00 is equivalent to $19.00 today. Yikes! That was mighty expensive back in the day.
I was just thinking back to around 2000 or so when M1 was right around $40 a jug at Wal Mart.

DI was developed for the main reason of the much hated on here and elsewhere, "gummint" CAFE standards of course, but there is also the benefit of MORE POWER (in most cases), especially for performance applications.
I realize that means VERY little to nothing for most on this site, but I will take every single pony I can get.
Of course the best scenario is to have BOTH a DI system, PLUS a one injector per cylinder system (vs. a single throttle body injector), for both max power, and none of the intake valve, and LSPI issues.

Mentioned that it's 8.00/qt I did see Pennzoil synthetic quarts for that price but individuals are always unreal these days.
AMsoil haters can stop witching on about the price.
