Engine oil Mobil or Shell

I just go to Walmart and buy the big jug of mobile 1 high mileage engine oil and the most expensive oil filter I can find and just do the oil change in my driveway.

I use the Mobil 1 just like the sticker Porsche put on your car…

I've tried various combinations that include the mix of m1 5-40 with 5-50 but have now for many years kept it simpler w/ Mobil 1 5-50 every five thousand miles. It purrs as one would expect from a 195,000 mile 996 Turbo.

I have used Shell Rotella T6 for 19 years on this engine with no issue.

My Saab (2003 9-5 Arc Wagon 3.0 turbo) has a sticker that says Mobil 1

Mannol 5W30 the one with JP at the end

Shell Helix Ultra 5W40 if you like to experiment, will make your bug quieter, but you will discover other noises (like tires, rattles of the trunk cover, gear noise, compressor of aircon).

To be honest, the mobil 1 ESP 0w-20 is a fantastic oil and meets those specs and is at walmart for $8/qt

Shell Rotella T6 5w40 and Tokyo Roki OEM filter all day everyday.

Both oils significantly reduced oil consumption

I found Mobil 1 0W-40 to allow a lot more timing chain and lifter noise, especially at startup but even after, then switched to Castrol Edge 5W-40 and the noise suddenly wasn't there. I've used it ever since.

Syn 3 is garbage. I typically run mobil 1 full synthetic (twin cam) or motul and motul for other stuff since they have dedicated lines for primary, oil etc.
