I've posted before that I've always had my cars' oil changed at Valvoline - different cars and different locations on both the east and west coast. I've never had a bad experience at one and in fact always leave them great feedback. They're fast, polite, don't upsell stuff - just occasionally recommend possible services needed - like diff fluid, and have never damaged any of my vehicles. I really believe the company has integrity. And I like their oil.
OTOH, I once had my oil changed at a Jiffy Lube when I was far from a Valvoline location. What a terrible experience. They gave new meaning to 'upselling' including recommending fixing chips in my windshield for 'free' if your insurance covers it. Total scam imo, that drives up everyone's premiums. Jiffy Lube is heavily franchised and it has been my experience in life that franchised businesses - whatever they may be - are often bad about trying to load you up on extras and things you dubiously 'need'. This comes from the insane costs franchisees have to deal with when having a parent company. Regardless, I will never be using them again. Not sure if Valvoline locations are ever franchised, but if they are they've avoided my previous comments.
