Engine oil LIQUI MOLY or PENNZOIL

I would take a good look at the brake fluid and stale gasoline but the rest should be fine.

Synthetic oil change is now $125 at the stealership so Ibu my own 0/50 Penzoil and a high quality filter every year, and vacuum out the Hybrid Traction battery filter myself

I use 10W/60 LiquiMoly 365 days.

Unless you are tracking the car you aren\u2019t going to see a difference. I use Pennzoil ultra platinum and a wix filter on my daily\u2019s.

Pennzoil Ultra Platinum, better than mobil 1, but also I am pretty sure all oil is within a few percentage points of performance anymore anyways, and it really doesn't matter as long as you change it when you should.

Luqi Molly 10w-30 with K&N filter in the winter. Mobile1 T4 10w-40 with K&N in the summer.

Liqui Moly full synthetic. 2qts 10w40 and 1qt 10w50 with the factory Honda filter.

If changing oil at 15k kms interval has served you well for 2 lakh kilometers, then I'd recommend sticking to it instead of switching to an oil with long service life. 30k kms oil change interval claim is a big stretch. I've used LiquiMoly 5w-40 with my Polo 1.2L TDI. Drove it close to or may be more than 20k kms over the course of 3 years until the check engine light came on. Immediately changed to OEM engine oil and for some reason the check engine light went away. Except with LiquiMoly, I've always changed engine oil at 15k kms or 1 year whichever was earlier. This is what my car's manufacturer recommends and I'll follow it even if I use LiquiMoly again.

BMW switched from Castrol to Penzoil years ago...but both cause oil starvation in The S65 motor
