is it true once you go with synthetic motor oil you cant go back and use regular motor oil?
thats what the guy at the parts store told me and i just want to varify it.

thanks

 

yea, that's what i've always heard as well...synthetic is better anyways...

 

i wanna switch back because its getting way too expensive, no more funds, low on money

 

From the articles I've read, it makes no difference as long as the correct rated and type of oil is used as recommended by the manufacturer. Synthetic oil is made partly with organic oil, its a blend.

 

the interval between oil changes should be longer with synthetic right? so that would offset the more expensive price of synthetic. ( eventually)

 

yes that is very true.............

 

From what I've read you can't switch back. The reason is because the synthetic oil sticks to the metal parts and doesn't allow the regular oil to come in contact with the metal. So as the synthetic starts to wear down the metal doesn't get the proper protection it needs because the synthetic oil won't allow the regular oil to take over. I've read this more than a couple times on this board, not saying it's the exact truth but it seems like many people agree with it and it sounds feasible.

 

it's BS by the oil companies just to get you not to switchback.

Maybe, but I ain't riskin my baby on a hunch.

Like the man said you can stretch your intervals further. Put a good oil filter in it (Frams are crap for the record) and you can easily get 4-5k out of it. That will more than offset the added cost. Besides I'd pay more to be able to go a month or two longer without changing the oil anyways.

i'm not saying i would switchback either cause i'd much rather have the better oil in my motor and have it last longer too. there should be reason why you can't swithback though since it says on the bottle it's compatible with conventional oil.

 

I have had many encounters with people from Moble and Ashland oil, ( think valvolin). It does not matter what oil you use, synthetic or conventional. You can at any time switch between the 2 and will not hurt any thing. If the oil companies wanted to make more money then they would never tell you this. Also with Mobile One and ONLY with Moblie One you can even mix syn. oil with conventional if you have to. Oil companies want to make it as versital as possible to the comsumer. To give you an idea we work on a lot of BMW's and Mercadies here at work and there factory oil interval is 15k miles with syn. Moblie One. You should still check the level every 500-1k miles though. As top off oils they tell you that you may use Mobile One, Havilin, and Kendal. The Kendal is a conventional oil not a syn. oil. If you think about it why would these car makers set this type of interval and tell you to use conventional with syn. if it was not safe. Those are expensive motors to be replacing.

If you would like on the Mobile web sight there is a whole wright up on this topic from the engineers.

 

yes (man I hate long drawn out answers )

Regardless of what anybody says, there is no problem with switching back. Now you don't want to be mixing large amounts of each with the other. But there is no problem with one oil type mixing with just small, residual amounts of the other.

 

thanks for the info guys
