So while back I got a Pennzoil Conventional and filter deal at advance auto, gave that to the neighbor for her 04' Cavalier. Today at lunch, I ran to the Autozone and got Quaker State Conventional 5w20 and a STP 6607 filter. The idiot counterguy, told me I should get Mobil Super 5000 or Valvoline Nextgen, cause the QS he used gunks up a engine. I told him to shove it and ring up my items. I paid and told him I know people that have used Quaker State Conventional and Pennzoil Conventional for years without blowing a engine. He just stood there like a moron. Have you guys encountered this like me? The guy had to be like 19 yrs old too. How many of you gentlemen and ladies have used QS and for how long? I have used it for about 6 yrs now. I have some Kendall 5w20 synblend I am going to use or do something with.
thanks in advance,
adam
