club lexus : You would think that because race engines use high octane gas, it would add HP,,, nope race engineare high in HP because they run compression rations that would cause rocks to detonate. The higheroctane gas just keeps the cylinder from imploding on the 1st stroke...I'm not an petrol chemical engineer and you may want a more complete explanation, try this:There is probably a simpler, more preliterate explanations somewhere, maybe someone can help findit...Net: If your engine is happy with 87 octane, you should be happy...My mileage is 22.6 around town on 87 octane gas/corn-alcohol L-cheepo,, it' all we get on thisIsland,, no knock, I be happy..JimmyAn Old Parrot HeadIn the Conch Republic,Just South of RealityIt's completely safe to use lower octane fuel. The engine automaticallyretards timing to avoid knocks. However, like Mark mentioned, you will loseperformance.No way you void your warranty with regular fuel. The owner's manual evensays it is OK to use if premium is not available at the time. My VW turbodiesel doesn't say it is OK to use gas in a pinch, there is a reason for thedifferent advice.Why is there a certain "class" of Lexus owners that get into this regular ofpremium fuel discussion? Premium is about a dime more per gallon where Ilive. Let's put some figures together here. If you drive 1,000 miles at 22miles per gallon you will use about 45 gallons of fuel. If the premium is1.69 you spend $76.82 per 1,000 miles. If regular is $1.59 per gallon youspend $72.27 per 1,000 miles. The difference is $4.55 per 1,000 miles. Ifyou drive 12,000 miles per year the cost difference is about $55. An"average" driver puts 12,000 miles per year on a car. Seems silly to detuneyour car and risk accelerated engine damage from light ping for fifty bucks.
club lexus : All good points, my response was simply to the person who implied you wouldvoid your warranty by doing this. That is not the case, and I said justthat.SullyI am not disagreeing, but in Colorado, generally premium is about $.24more per gallon. And, our choices for octane are 85, 87, and 91.Well thanks for the info. Most replies from this group and club lexus leantowards premium for one reason or another. In my case the difference is$200 - 300 a year. Small change compared to the investment I have in thiscar. BTW, in california the difference between regular and premium gas isabout .25 - .30 a gallon (everything seems to cost more here and especiallyon the coast).That sounds low - here in the Northeast it's around .30 difference .. For themiles I drive and the mileage per gallon I get, that translates to more than$500 a year difference. I still do use premium - I couldn't stand any sloweraccelleration..but that's still pretty significant.Hehehhehe. Haven't seen the word "gelt" in a long time. Agree with youabout cheapskates and fuel in a performance car. Are these the same people whostretch out their oil changes to 10K+ miles and then bitch when their enginessludge up?
club lexus : Not much going on with the Lexus forum at Club Lexus... so I'mbringing my questions here. I have a '90 LS 400 which has 138,000 miles on it and doing well. It had a power steering pumpproblem at 110,000 miles and was replaced by the previous owner atLexus of Chattanooga for $1100. Now that it's in my hands... the car has been doing fine for the last4 months but it just started making a high-pitched whine, especiallywhen I turn the wheel either to the right or the left. The previousowner also just fixed the right front wheel bearing before I bought itfrom him but I suspect it's the power steering again.Question is... do I send it back to Lexus or can I save some money andhave an independent foreign motors shop handle this one? And whywould the steering go out so soon... if that's what it is. I'mwanting to keep the car for a long time but not if it's going to be aheadache.In no way would I ask an obvious question just to insult your intelligence, but may I assume thatyou have checked the fluid level?On Sun, 16 Jan 2000 22:33:09 -0600, "Esso Extra" wrote:
club lexus : About a year ago I bought a '94 LS400 with 100k miles on it. It's inabsolutely showroom condition, with all maintenance records. A trulywonderful car. So here are the questions: When it's cold in the morning,my instrument lights don't turn on until after the car warms up,approximately 5-10 driving minutes. Has anybody else had that problem? Thedealer said it would cost $1000 (!!) to repair by replacing the integratedcircuit that controls all the instrument light. What do you think?Next question: are there any service manuals out there that are worth themoney for my vehicle? I've been unable to locate anything.And there's more... my vehicle has a 6-CD changer in the trunk. It worksfine, but is somewhat inconvenient. Can it be retrofitted to somewhere inthe cabin?Oh yeah, I forgot... the tape deck should probably be replaced; has anyonehad any experience with that?I didn't mean to ask so many questions; sorry about that... Thanks foryour help.If that circuit board is out be careful. The dealer got me for about $1700dollars. First of all they couldn't find another one in the USA, so theyreplaced all of the gauges. Make sure that they check the grounds on theigniter because I had an issue there. My car was doing what you describefirst before the speedo stopped working followed by the tach etc. I'm in theClub Lexus group its very informative. As far as you changer goes I had onetoo. I've since replaced it with a smaller aftermarket one. I'm an ex stereoinstaller turned computer geek I still do alarms remote starts etc. If youhave any alarm questions about your LS. I can answer them gladly and audiotoo. Good luck. If you are in the greater Seattle area I have a Lexus MasterMechanic that moonlights.
