Engine oil VALVOLINE or Shell

Use good oil, always helps. Try valvoline restore and Protect. Quieted my engine down a little

Tried other brands pero Shell pa rin talaga

I only run 5-40 Full Synthetic on my Armada and all my vehicles in the past. I've never had an issue and only changed the oil once a year or whenever 7500 miles hit. As for what brand, Shell Rotella T6 5-40.

Rotella T6 5w-40 is what I’ve ran in the car ever since it was tuned and I get great feedback from blackstone labs when sending in my oil for analysis.

I used to use Rotella T4 as recommended by many on the forums. It was fine but I switched to Valvoline 20w50 because it has the additional Zinc like the Rotella T4, and a bit better film strength which protects bearings at high RPM.

My experience sa long ride, malamig sya for my scooter. Ayun yung ginagamit ko after mag general pms. Better sya sa ibang nasubukan kong engine oil like petron.

I’ve had good luck running Valvoline VR-1 in engines with flat tappet cams.

Valvoline VR1 in whatever viscosity is suitable for the season and the VR1 has plenty of zinc for old engines.

I’m running basic conventional 10-30 Valvoline. Oil changes every 3500 miles. 185K miles, track if 5x a year

Valvoline is pure trash. Hardly any additives between any other lines of oil compared to competing brands.
