Switching between Engine Oils Synthetic and Regular?
I usually put in Synthetic on my old 92 Passat, but the I went to the
garage, they put in regular oil. No difference noted. Last time, I put in synthetic - no problems. There is a small leak - so on trips when I have to top it up - some places do not have synthetic - so I use regular. For the majority of oil changes - I do put in regular. But with the cost of oil going up everytime. I just might stay with regular. Does anyone forsee any problems with doing this (switching/mixing oils)? Thanks, Tmuld. |

I dont have any evidence to point you to, but you should NEVER EVER MIX regular dino oil and synthetic. I also highly recommend AGAINST switching oils. Either stay with regular oil or stay with synthetic. |

Either stay with regular oil or stay with synthetic. Why? To the original poster... mix the oils that you regularly mix in a clear glass, and watch to see if they separate or do anything else funky. If they don't, you shouldn't have any trouble mixing them in your car. I stick to one brand of oil, but I really don't see any reason why switching (assuming you're using the correct grade/viscosity/etc.) would cause any problems. If there's a reason (other than myth) that I'm wrong, I would like to know. Craig |

All synthetic oils I've ever used explicitly state on the label that they are 100% compatible with regular oils, and there's no worries at all about mixing them. You will compromise the qualities of the synthetic by doing so, but it won't do any harm. I've done exactly what you've described, many times, and I've never had any problem. Check your oil's labels. |

I've been switching back and forth for years (>20) in multiple brands of
cars and have never had any engine problems. When synthetic oils first came out (and everyone was hesitant to use them) I read a suggestion in a book on extending engine life that recommended adding one quart of synthetic with every oil change to get some of the benefits. Now Valvoline makes a product named Durablend which is exactly that, synthetic and dino oil mixed together. So I'd say you are fine.

With a comment like that you may be banned from here and doing oil changes.
As for my 2 cents... as the name implies "synthetic oil" is man made oil. Don't worry, be HAPPY!

For me, the synthetic oil would taste better than DR.Pepper.

Oil change intervals, brands of oil, and dino or synthetic are
subjects of religious or political zeal. Not any worse that the vastly experianced 21 year old driver telling the old farts that a 1.8T is vastly superiour to a TDI. Both get you to the office when you spend an hour in bumper to bumper traffic. Back to oil. Both oils lubricate your engines. Most folks get rid of the car before they would see the questionable benefits of synthetic. This comment coming from someone who has used Mobil synthetics since about 1984.
