Hey,
Is it true that once you put synthetic oil in your car, you can never put regular back into it? Even when getting your oil changed?
Thanks!

I totally agree, but once you start using Synthetic you won`t go back, LOL
Agreed.... That is a pantsload.

Like this forum, but for oil.........
I believe there are more myths:
Synthetic is so slick, it will go through your piston rings if you use it after 3000 miles.
You cant use synthetic if you have used regular oil for longer than the break-in period.
A 60k+ mile engine will die with synthetic in it.
There are a lot of stories. I use only Mobil 1 and have for 15+ years. Good or not, I feel good. I have cases of it in my garage, I bring it to my oil changes. Along with Sunoco 94 octane fuel. For the few extra bucks, who cares!
I`m a die hard Amsoil user. Every fluid that needs changing gets changed with Amsoil.
Yup, it`s a myth. Have you ever noticed "Synthetic Blend" oils on the shelf with the dino and synthetic stuff? If they can mix it in a bottle, there`s no reason why changing back and forth in the engine would harm anything.
It`s a myth, although I wouldn`t be switching back and forth. I`ve been using Lubro Moly and then Elf synthetics in my turbo Volvo for over a decade and she has always been running great. Regular changes are still key, I usually do so well before it`s recommended (6000 kms on average).
yup those are myths. at rx7club some of us believe that we shouldnt run synthetic oils in rotary engines but the truth is that you should never run craptastic synthetic oils, so its ok if you go for the big brands like Mobile 1.
Hrm...any proof to this from an actual oil company.
What or would there be a benefit for going from syn to reg?
meh i got this though lol.. though its written by a respected rx7club admin... and it applies for rotary engines lol...
"Can I use synthetic oils in my Rotary engined car?
Yes and no. Mazda offically does not recommend the use of synthetic oils in rotary engines, however, long term and racing use has shown that the better synthetics (Redline, Amsoil, Neo, Royal Purple, Mobil1) are perfectly fine to use in a rotary engine, and will generally result in a 1 to 2% horsepower gain. However use of poor quality synthetics (like Valvoline, Castrol Syntec, Havoline, Etc) will result in build up due to high ash content left from these oils when they are burned. It is believed that is why Mazda did not recommend synthetics, because the couldn`t pick favorites."
Why go back to dino when sythetic is a lot better, need proof that you can go longer during oil changes?? Then here you go http://theoildrop.server101.com/ubb/...c;f=3;t=003511
**Take note this oil sample has approx 10 hrs of me moving from south Fl (near the Keys) to SC (80-90 mph) and two trips back to central FL (6 hrs each way; 80-90 mph). Add to that some "spirited" local driving, and they want me to go 6,000 miles for my next oil change** Cost of each oil change $14 using Motorcraft 10w30 sythetic blend ($2.07 each@wallyWorld) and Motocraft Fl1a oil filter($3.xx) that only $28 a year
