I own a 2004 4runner and over in NJ there is a gas shortage due to the storm. The lines are crazy and gas is in high damage. My question is I always fill my gas tank up with regualar gas, and this time around I was able to stand in line and get about ten gallons of regular gas into my tank. I stood in line today and was only able to get 5 gallons of premuim into the portable gas cans. Everyone is telling me not to add the premuim to my tank because "mixing" the two grades may mess up my engine. Can someone PLEASE but my mind at ease and set the record straight. I really don't think I can stand in line for 4 hours again.

No problem.
No problem whatsoever. You engine will advance or re**** the timing as necessary, and 87 + 93 equals ~89 in various proportions.

Lol...they have no idea what they are talking about. In"general" terms if u mix half 87 and half 91 u get 89.
Don't mix in diesel, obviously.
I used to drive a sports sedan e92 and I would often mix 93 with e85 which equals...RACE GAS!! who ever said that has no idea what they are talking about.

Or E85.....lmao...
Ok you must know me...people are always accusing me of over thinking things. I have a little bit of OCD in me. I only ask this because a friend of mine owned a 1995 Oldsmobile Cutless and when he added a different grade of gas his engine went good bye. I am thinking it was because it was an older car. I am by no means a car junkie just thinking thats all.

I would say even then in his Olds it wouldn't mess up the engine from mixing octane. Probably just coincidence that his engine went kaput.

No doubt you have at times thought you were getting regular and in reality were getting premium. Premium is carefully tracked from the refinery to your tank and the occassional pipeline, tankage, rail, or barge loading process will contaminate the premium with a little regular, kero (jet fuel), or diesel.
That mistake/accident causes the whole batch of premium to be downgraded to regular.
By the way, regular contains up to 5 percent transmix, premium zero percent. Transmix is the mixture between pipeline batches (the interface between two batches has a mix of both batches - mixing, and growth of this interface, occurs along the way).
Transmix is usually a little diesel or kero. The mid-stream transporters of refined petro do not allow anything foreign into jet fuel or premium or diesel. Up to 5% of anything that will burn is legal to put into regular gasoline.

I own a gas station in TX and I can tell you that mixing E10 or less type fuels is OK. Most modern gas stations only order regular unleaded (87 octane) and premium unleaded (92 octane for my stores). There is a device underground, with the storage tanks, that mixes the two to make Plus grade fuel (89 octane).
E10 = 10% or less ethanol blended fuel.
Hang tuff & be safe!
On a side note...gas station owners started the "cell phone spark" myth because idiots yapping on their cell phone tend to forget to remove the fuel nozzle from the car when driving off. It's gets expensive having to buy new nozzles, hoses, adaptors, pins etc...a couple times a month.
