The OLM just seems like a mileage counterI'm going 5k on my 6.6 gas with DexosG2 until warranty is up then probably switching to HPL, interval TBD. Even with lots of towing the OLM calculates past 7k.
4000 miles is a good interval... but depends on hours and weather conditions, along with oil brand/grade that you're using which is???What do most do for a GDI only engine?
I've been doing 4,000 miles on my 6.6L GM engine.
Is there any benefit to using HPL and extending the drain?
I worry about timing chain wear from the soot build up.
I've been using Valvoline 5w30EP4000 miles is a good interval... but depends on hours and weather conditions, along with oil brand/grade that you're using which is???
If there is an OLM, at 4k miles, what is the percentage left?
I don't see any benefit in extending intervals. SP/GF6 addresses timing chain wear.
For more info concerning your interval and oil, send out a sample for analysis.
Other things to worry about.... long term ownership and intake valve deposits
Do keep those injectors clean by using toptier fuel and/or occasional bottles of quality FI cleaner.
In winter mostly water. In the summer it's all oil. Maybe 5oz in 4,000 miles.What do you see in the catch can?
I saw a YouTube video with a GM engineer explaining the PCV system. It must do something or they wouldn't spend the time and money and put it on the engine. Maybe you'd get 8oz instead of 5?In winter mostly water. In the summer it's all oil. Maybe 5oz in 4,000 miles.
GM is supposed to have some advanced PCV system built into the valve cover.
It doesn't work.
GDI = 4,000 OCI for me using D1 / Gen 3 rated 5W30 synthetic oil from M1 , Valvoline , Pennzoil or Quaker State Full Synthetic from WM .4000 miles is a good interval... but depends on hours and weather conditions, along with oil brand/grade that you're using which is???

3-4k max, the extended drain oils have the tbn and shear stability but that does nothing when fuel dilution and carbon soot are your major problems, it must be removed via an oil change.What do most do for a GDI only engine?

3,500 to 4,600 mile oil changes for the winter because of fuel build up in the oil.What do most do for a GDI only engine?
