Well, I decided to switch from dino to synthetic after 30k on the car... so I went to jiffy lube, had it done and the next day, my car seemed to struggle after ignition kinda like puttering, but then it would clear up... so after two weeks I decided to add an additive ok'd for synthetics... and the next thing you know, my car dies while it idles at the light (I have a manual)... so I took it back to jiffy lube to explain the problem, and they said it wasn't the oil. He connected a code reader to the car and it said that one of the cams was thrown off sync and that it wasn't because of the oil... I thought he was full of **** and so I took it home and called the guys at Precision Z in Canoga Park,Ca (www.precisionz.com ask for Ed, he's a good guy that helped me out) and he said my problem was that I added Mobil 1, so he said drain it... and refil it with an oil I preferred, not Mobil 1 though... so I did... and now it's fine... My question is.. has anyone experienced something of that nature with Mobil 1??? I feel like I want blow up Mobil Oil Corp. (anyone wanna join?) They made my pride and joy almost croak .

 

wtf, do you work for castrol? sounds like a bunch of bs to me.

 

never take your "pride and joy" to jiff lube that was your only mistake mobil 1 is fine !

 

Do I look like I'm boasting castrol??? I just explained what happened to my Z, and all I'm asking to see if others have had probs with Mobil 1? geez...

 

nope.. i always been using mobil 1 and i had no problems with it...

 

why would a specific motor oil harm your engine like that? It's not because of the mobil 1, that's for sure. Your car can even start fine with less than one quart of oil in the car.

 

I tried to run mobil 1 in the z and it straight ate it. Switched back to normal oil and it still eats a little of it but not as much.

 

that's weird...I've been using Mobil 1 for 5 years now in all my vehicles...from all sorts of Hondas, Lexus, and the VQ35 and ZERO problems...

 

I haven't noticed any problems. Weird.

 

Motor oil is not responsible for the symptoms that you mentioned. Nor the solution.

 

Been using Mobil 1 full syn. for my Z for the past 4 years, no problems

But now I use Enenos, the purest synthetic u can get from Japan/EU, it's cool to have JDM oil on your car.

www.Eneos.us Hard to find a place that sells this, they just started to advertise in the US this year

 

What you are describing sounds more like a vacuum leak or foiled MAF sensor etc. Clean oil NEVER causes the engine to "putter".

 

Been using Mobil 1 for 4 years and over 85,000 miles. No problems.

 

LOL @ this thread. I am going to have to call Ed at Precision Z and ask him what his philosophy behind this is.

 

All I'm saying is that I wanted to know if someone else had problems or not, because I had a specific problem which occured only when I upgraded the oil, and after changing it back to regular, it's gone.

As for Ed @ Precision Z, his exact words were "that's your problem, you used Mobil 1..." He's an expert, I trusted his opinion, and thanks to him, my Z is back to normal...

 

he probably made that comment because he doesn't prefer mobil 1. I think you took it the wrong way. I've notice a lot of places have done that to sell their oil or they have a oil that they swear by.

 

 

Theory:

His engine has slight wear, traditional oil cannot pass through the gaps but Mobile 1 has enough viscosity to do so, thus fouling his fuel/air mixture.

 

You went to jiffy lube that explains it! Maybe they put tranny oil of some kind!

 

Slight wear my ***! My 95 MBenz C36 has 96k+miles. Been using synthetic since 70k miles with no issues. Doent burn oil and I drive it hard.
