Well he might be kind of right. There is one machine I have ran synthetic in for it's entire life without changing....

I wouldn't even think of running synthetic in my mower lol. It's just a mower :-P

Hey, besides, I like touching my car! Changing the oil every 3750, I know all about that, (it's not your grandpa's oil anymore) blah, blah, blah, but hey, if I wanted to be prudent and penny pinching I would have bought a CRZ hybrid thing and ran 0W-20 synth.

Yeah...I did it mainly as a joke. I had a spare bottle or RP on the shelf and figured it had to be better than the crap they included in the box. Sold that mower to my brother several years back. Still runs perfectly.

so is it better to run mineral or synthetic? isnt it better just to follow the instructions of the owners manual?

mike444 · 06-25-2014, 12:52 AM

I have done many a Google search on Synthetic vs Mineral oils and how synthetic oil works. The fact is, the fundamental difference between synthetic oil and mineral oil is synthetic oil is manufactured chemically and mineral oil is natural, obviously right? But what that means is the individual molecules of oil in synthetic oil are all the exact same size due to the manufacturing process, nothing in nature is ever exactly the same.

This allows the synthetic oil to break down evenly where mineral oil has varying molecule sizes that cause the oil to become thicker the longer it is used.

i thought mineral oil is just distillation from crude oil which means that its thicker than synthetic? wouldnt you want thinner oil especially cuz our car gets hot?

From what I've read, and this is just my opinion, it seems like synthetic is the way to go, the only disadvantage is the cost increase.

It's thicker than synthetic because of the varying size of molecules. Synthetic is engineered to coat engine parts, so the viscosity doesn't change throughout the life of the oil.

thank you very much exsanity... synthetic is what i use, just wanted you guys to clarify

mike444 · 06-25-2014, 01:11 AM

So, not trying to turn this into a synth vs. conventional here..theres plenty of that already.

Let me start off by giving facts about my car and where I live and my driving style:

- I live in south fl, so its hot/humid virtually year round
- Manual 09 Z
- Drive like a granny(not an understatement lol)
- No tracking or racing(if you do thats cool)
-Sport pkg

So, from what I read, looks like I might experience some leaks but only for the first change because its "cleaning" the gunk out.. w.e that means. I just don't want the car to take a step backwards by switching I understand it better for the car but the whole point of the thread was to see if you guys have any input on if its a step forward by changing now at 66k. Anyone dare to give a straight answer?

Also as for the tranny fluid, I have also read and been told "If it ain't broke, don't fix it" I have never changed the tranny oil as mentioned above, I find the shifting normal but maybe I'm just a dummy lol what are some symptoms of our Z's screaming "I need a tranny oil change please!"? Same question refers to the VLSD.

As for brake pads I ordered: "Wearever Platinum Premium Ceramic Pads", if theres any reason I should return it and get something else by all means let me know.

From an engine standpoint I see no issues with it but I will never switch to synthetics in any car I own based on my experiences with it creating a leak.

This! Anyone think this could be a consistent problem in a Z with 66K?
