My honda accord ex 91 is running exellent since i changed the ignition wires and spurk plugs. it has 107,000 miles, manual transmision. for more power and gas saving, what kind oil motor and gas should i...

With that many miles there is no point in putting synthetic oil in the engine because it will probably be too thin and cause the seals to start leaking. Keep the oil changed regularly (every 3000 miles) and use a brand name 5W-30 grade oil like Mobil1 or castrol. As far as gas goes I would put a tank of high octane gas in about once a month. You can try using high octane all the time but check your mileage per tank on the regular grade and then after you've filled you car about 4-5 times with high grade so you can see if it really is making a difference. Also check your owners manual to see if it recommends higher grade gasoline.

I accidently put super unleaded gas.on my VW beetle 2002

That is not a problem it is actually recommended that you use premium 93-94 Octane fuel, if you put turbo blue (115) in it that would be a problem but 93-94 octane is the VW recommended fuel type.

Was told to use premium 89 octane gas only this true?

This is true. The only time you need to apply gasoline with higher octane is when preignition is present. If it sounds like marbles are bouncing in your engine when you are driving then get higher octane. However if the car is in good mechanical condition (cooling system, oil serviced regularly) then 89 octane is perfect.

What grade is gas is good for 1999 toyota camry

Hello, and welcome to FixYa.
Please allow me to assist you with your question.

The 1999 Camry can run on any grade of octane, 87, 89, 91, 93 or 94. However, it will run best on 89 octane. That is what I use in my Camry, and it is also recommended to our service customers in our shop. You can safely use 91, 93 or 94, but those higher grades really will get you no better results; as the engine is not designed for that octane. It will run normally, on the higher octanes, but keep in mind that it will not run any 'better'.
You may have heard in the past that people 'treat' their car to a tank of 'premium'. That really serves no good purpose. All that does is costs you more money for a tankful, so adding premium at random intervals is not recommended.

I hope that this answers your question.
Thanks for choosing FixYa for assistance.

Im curious about octane in fuel and what it does. I have a Nissan 350Z that requires 91 octane. Now if I were to put 94 or higher, would it improve performance or fuel efficiency at all or is it just a...

Octane is an added ingredient that burns more efficently than gasoline..use the 91 octane rating that your owner's manual specifies. Lower octane will degrade performance, higher than 91 is wasting money because it has more octane and is more expensive, but does not improve performance.

Want to buy s type jag but i need to know what type gas it uses

Jaguar recommends the highest grade of gas for the best overall performance. usually this is between 91 and 95 octane, however many of our Jaguar customers just put the mid- or low grade fuel in the car. Now you can do this but the performance and in most cases the gas mileage wont be as good as the premium gas.
The way I see it is if jaguar did all that testing and engineering for that car and they came to the conclusion that it works best with high octane then i would do it. But hey, its your choice, i hope i helped you out.
