Mixing synthetic and regular oil!

Ethereal · 01-07-2008, 03:30 PM

Ok so I just used 50/50 blend of synthetic and regular oil when I changed my oil today.

I want to see once and for all if you can or can not mix synthetic and regular oils.

I'm using Spectro S4 regular oil and Spectro synthetic. Both are 20/50 weight.

I hear that it may mess up some gaskets but I think thats just an urban myth. I believe that when synthetic oil first came out that was the case, but some mad scientist was able to solve the problem..

What do you guys think?

I'd agree Choco, except a quick search turned up 3 results where the theory of Mixing was validated.
Below is one.

Mixing Synthetic and Conventional Motor Oils

Question:
Mixing Synthetic and Conventional Motor Oils
Can you ever blend synthetic oils and conventional oils? If so, what is the ratio?
-- Julie Patten, Des Moines, IA

Answer:
Yes, synthetic oils can be blended with conventional oils. Several companies, including ExxonMobil, market synthetic blends which are a combination of synthetic and conventional oils. In the case of ExxonMobil, the ratio of synthetic to conventional oil in these products is considered proprietary information.

2qt Valvoline Durablend 10W-40

no real reason I do it, just do

Nothing wrong with it. You just lose some of the benefits of the synthetic.

It's not going to do anything at all except lubricate your engine. Oh- and it'll slowly change to a darker color.

Just wondering, is it a cost thing?

Nah, I'm filming my own episode of mythbusters....

I wanted to just up my old gallon jug of oil before I started using the new one and I thought they were both synthetic before I started.. Oh well..
