Clean your mass air flow sensor, could be running rich because its dirty, causing extra fuel dilution.
MAF cleaner is like $10 for a can that will last for 10ish uses
Or it could just be because of the direct injection and turbo. Seems like a lot of these new low displacement forced induction...
Oh I missed the viscosity figures the first time. Doh. You went from about 13 to 8.5. Thats a lot of fuel leaking into the oil.
Seems like if the hpfp were leaking that would cause a drop in performance.... Unless the rail and line pressures just seep into the valve cover when you shut off the...
$25 OBD2 Bluetooth adapter from Amazon, bafx brand. Then torque pro app. Or stop by a parts store and see if their code reader will pull live sensor data. Most these days do
Instead of pulling the injectors I would check the long term fuel trim at idle and at #
2500 rpm. Leaky fuel injectors will show a negative ltft of -%10 or greater. Ideally your ltft will stay within +/- 5% if all fuel metering and injection systems are running optimally.
Leaky injector will...
Castrol Magnatec 10w30 has about the best NOACK of any 10w30, 6.9.... with a 100c viscosity of 11.6cst. Should be fine for 7.5k miles, up to 10k
The castrol edge 0w40 is about 12.9cst @ 100c, and is BMW LL-01 certified, so it should be generally good up to 15k miles unless the car has excessive...
Flat tappet cams on that engine, id suggest trying magnatec. It has quieted my zx2 valve train on startup, from the esters coating the surfaces. This should lower iron shedding

Should work great. I have an 07 cobalt which consumes 1/2-1qt of oil over the 9-10k mile oil change interval. 3000 miles ago I changed it to mobil 0w40, which is a euro spec oil, almost a 30 weight at 12.9cst @ 100c. It has stopped the oil consumption and it runs great. This oil also has a very...
I've ran magnatec 5w30 full and partial synthetics out to 8-9.5k miles without any "goop". The engine consumes about 1 quart of oil over that time period. Whoever had goop must have had a separate issue, like blowby turned the oil black and a head gasket crack created the goop.
The magnatec...
I've put 60k miles (now at 160k) on my escort zx2, which has the zetec DOHC with flat non-hydraulic tappets. I've used API sn oils the whole 60k and the engine seems fine, buckets and lobes don't look abnormally worn. For the last 25k miles I've run Castrol magnatec, which has polarized esters...
Magnatec 10w30 would be a good choice. Thicker for 30 weight, 11.6 CST @ 100c, NOACK of only 6.95. Would be better for the extra strain on the engine from towing. I think this is one of the lowest NOACK oils you can buy, aside from pennzoil ultra platinum (but that test was from like 4 years...
It may or may not be good, hard to say. Generally, the old rule was when TBN reaches 1/3 of its initial reading, then its done. Most oil has I believe most oil has a starting TBN in the range of 6-8, so its borderline.
I ran castrol magnatec syntetic 5w30 to 9,500 miles in my cobalt and the...
All air filters increase in dirt capturing efficiency with use. Of course you get a proportional increase in restriction though.
Wear numbers look nice and low for the mileage.
