Engine oil VALVOLINE or OEM Mazda

I really liked Valvoline, good quality, reasonble price.

Valvoline Restore & Protect or Pennzoil Ultra Platinum are also great oils to run and clear up and baked on sludge.

Buy Valvoline oil, and maybe it's a good time to switch to 5w-30 in it.

I only run Valvoline VR-1 40-wt in my air-cooled VWs

I tell you the stuff really works. My 2009 Matrix used to burn oil before I switched to Valvoline Restore and Protect.

i honestly have no way to prove if it works, but i started using it in my ‘98 corolla about 20k mi ago (known for burning oil due to flawed piston design) and have noticed a significantly lower oil consumption rate, which was almost 2qts every 5k down to less than half

I normally dont buy into stuff but my vette was burning oil, Id see a big cloud of blue smoke after I let off after every pull, few thousand miles of this stuff and I stopped seeing it.

That stuff ROCKS! Cured my stuck piston rings issue on my 201O Acura J37 engine.

zu viel Kurzstrecke. mach mal nen Ölwechsel und lass den wagen dann mal richtig auf Temperatur kommen.

I use that Valvoline, sometimes throw in random fully synthetic oils I get in bulk from an auction. I feel like it contributed to a rear main seal leak. Thinking of switching to a 5w40
