Mixing Synthetic with Conventional Motor Oil
I was thinking that before taking out my 29 Tudor for the first time this spring, that when I change the oil I would replace it with a good synthetic.
Would this be a problem because of the amount of conventional oil leftover in the dip tray? Or should I drop the oil pan and clean out all of the conventional oil? I might add that I last cleaned out the oil pan two years ago and I only have put on less than 700 miles since then. |

Re: Mixing Synthetic with Conventional Motor Oil
I think they say the two can be mixed with no problems but it never hurts to clean out the pan.

Re: Mixing Synthetic with Conventional Motor Oil
My 2004 Dodge Kadota runs on a "SYNTHETIC" BLEND!---My Friend Ron Strong @ R&R Automotive has used it for YEARS. He's a SUPER TECH & has done a radio talk show, called, "AUTO SHOP TALK" for 35 Years. I trust him TOTALLY & never even asked him the BRAND NAME!

Re: Mixing Synthetic with Conventional Motor Oil
As Bill stated, the major oil companies have been offering a "synthetic blend" for as long as they have been offer full synthetic. Go will be good to go.

Re: Mixing Synthetic with Conventional Motor Oil
"Both types are made from crude oil that comes from the ground. The difference is that synthetic oils are made from more advanced refining processes and are of a higher purity and quality than conventional mineral oils."

I wouldn’t be concerned about mixing the two oils. I would be concerned about the possible effect on seals and gaskets if you have an elderly engine. |

Re: Mixing Synthetic with Conventional Motor Oil
If you have only put 700 miles on in 2 years, you are wasting your money going to synthetic. Cleaning the pan after 700 miles would only be exercise for you and your tools, and may even precipitate a leak. Use the expensive oil in your modern rig.

btw synthetic blend can be up to 90% conventional oil (meaning only 10% of the bottle is synthetic. IMO go full synthetic)

Re: Mixing Synthetic with Conventional Motor Oil
I read a long time ago that all synthetic has a natural crude base.

Re: Mixing Synthetic with Conventional Motor Oil
Isn't it AMAZING that engines start, in REALLY COLD climates? On TV shows, they ALWAYS crank on the FIRST PULL! They must have had them WARMED up, already---LOL

Re: Mixing Synthetic with Conventional Motor Oil
I can speak from experience. When we lived in Minnesota, had an 8hp snow blower that I put Mobil 1 in and would start on the first pull after hitting the primer. Had an electric start, but was a lot of trouble to get the extension chord. Just hit the primer a couple of times and pull the starter chord. Did drain gas every spring, new gas and plug each winter. Engine was hard to pull with conventional oil, but was very easy once on synthetic.

Re: Mixing Synthetic with Conventional Motor Oil
I wouldnt even consider changing your oil at 700 miles............ as others have said.
I blend my own oils all of the time, reg with synthetic and never a problem. |
