1998 F150 V6 - Seemed like only yesterday (March 16th) when I hit 280,000 miles.
Out:
QSUD 5W30 with Purolator Gold Filter - I actually ran this a few minutes short of 10,000 with only one quart makeup oil required.
In:
Valvoline Synpower 5W20 with Wix Filter - I had this laying around. Actual change mileage was 289,614 and I anticipate running this until 300,000 before I change it again.
2006 Scion tC, 100k miles. Used PYB - first time since the break-in oil.
5w30, Pure1 filter.
Just seeing how it holds up after 99k miles of expensive synth!
So far, it hasn't died on me
1 week and a half ago. Mobile 1 5w40 TDT with Wix filters in my '04 cavalier. noticed a little oil consumption every 3000-4000 miles thought id give it a try. I Have ran 5w30, 10w30, SAE30 oils in Mobile 1 5-30 10-30, M1-HM 5-30 10-30, Royal Purple 5-30,10-30 Kendall 30WT, Royal Purple SAE30, Pennz Platnium 5-30 and 10-30, Rotella T6 10-30, now M1 5W40 TDT.
Ive read that these ecotecs are oil burners so hopefully the M1 TDT does the trick if not Amsoil will be the next step.
For some reason I believe oil is splashing under the pistons and burning off so if the M1 TDT is good enough to run through a nice hot turbo I hope it would with stand the heat from under the pistons.
