Engine oil Castrol or PENNZOIL

Honestly, I just use Pennzoil Platinum for the past 7 years. but now I feel like reliability depends on the user, just keep up with the oil changes at least every 3k and if you’re abusing, just watch your oil temps. I have 145k miles and I abused this car since I had it at 0 miles. Still original motor and tuned by Admin.

Since switching to Platinum there are no oil leaks and less than a qt. to top up between changes.

Pennzoil Ultra Platinum usually or Castrol Edge. In North Texas I’ll run a cold grade of 10w in summer and usually 5w in winter. 40 or 30 summer hot viscosity/ weight and 30 winter. 4.2 version of your 4.0 S/C AJV8.

I'm a Castrol syntec guy and I like Kirkland oil. So that's what my cars get.

I'm personally running Castrol in the BMW bottle.

Got some numbers for the oil pressure Water temp around 90-95C/194F. Ambient temp 28C/82F Oil 5W30 Castrol Edge LL Hot idle 20 PSI 2000RPM 60 PSI 3-5000RPM 70 PSI Looks okay?

My co workers wife had a high mileage Sienna 3.0. Oil leaking from every seal. We started using Castrol high mileage, it stopped leaving spots in his driveway and quit loosing 1.5 qrts between oil changes.

I have stuck with manufacturers till manufacturers recommendation is causing issue, like my gixxer leaked entire oil from companies estar engine oil, switched to castrol power 1, no leak, headache gone and happy riding on it for about a decade now.

Former BMW dealer employees have confirmed that the overpriced BMW oil is literally castrol edge.

Car has been at the stealership for three weeks. Same transmission TC seal leak. Bolts and seals also needed replacing. Car is 45 days old with 4K KM’s.
