Synthetic motor oil

I'm a bit of a car girl.  I've always liked being out in the garage and changing my own oil and doing basic maintenance, etc.  When I was 15 and going through driver's ed, our teacher said we had to learn to change a tire.  Well, my dad decided I would learn on his Ford Ranger and I realized changing tires is dirty and hard work.  I've only had to do it a one or two times since then and I'm thankful.  I'm also thankful for the skills my dad taught me to maintain a car, it has come in very handy as it makes me feel useful in the garage.

Recently I was at a Mindful Mamas meetings and we got to talking about synthetic motor oils and how they're better for our foreign dependence on oil because they're not made from oil.  While I agree with this, I also don't like all the chemicals that are produced for synthetic, but it seems six one half dozen the other, right?  So, I started researching synthetics and found out that they last much longer than conventional motor oil but are pricier.  So, I did the math...

O'Reilly parts store:
Castrol Syntec $5/quart (on sale, reg. $8/quart) = $25 for my SUV
Lasts about 7,000 miles
= $.0035/mile

Castrol GTX $3/quart = $15 for my SUV
Lasts 3,000 miles
= $.005/mile

So, it's cheaper to use synthetic + it's better for your engine :)

Are you willing to switch to synthetic?


  1. we have for a while, but recently, when I took my (very dirty) car to get the oil changed and mentioned that it lasts longer, the tech said "but it gets dirty and it will only last the same amount of time." I feel like someone is lying to me. I don't know if it is my husband or the tech.

  3. Good for you Bridge :)

    Paula, I think the oil change guy was probably trying to swindle you. But I could be wrong :)
