Replying to: garyh1 (Nov 16, 2006 12:21 am) Just drive and enjoy..... You may find the gas mileage drops enough on regular to actually justify mid grade on an economic basis. See what happens. Premium gives you the greater performance possibility. But the engine will be fine.

Replying to: tjohn (Nov 16, 2006 5:44 am) Thanks, tjohn and fin. So now instead of feeling stupid for picking up the wrong gas nozzle, I feel like a continual sucker for usually paying an extra 30 cents/gallon for premium. Hmm, not sure that feels so much better.   But thanks for your reassurances.
#8019 of 8360 Extended Warranty by cneuman Nov 17, 2006 (7:55 am)
Has anyone had any experience with purchasing an extended warranty for their LS outside of their home state? If so, what was the cost and experience?   Thanks,   cn
#8020 of 8360 Old Lexus LS 400 in Snow ? by 2driveright Nov 20, 2006 (9:47 am)
Does anyone have experience with the first generation Lexus LS400 driving in snow? I'm considering buying one to be a 3rd car that will be a winter car. I understand the early 400's were derived from the Toyota Cressida and if so, I do have a lot of snow/ice experience with that car as I had a new one in 83 - 87 and found it to be very good in the winter here in NH. The Cressida was also a rear wheel drive car and with only a limited-slip differential, it handled deep snow and icy conditions very well. It was a rare car having an inline 6, a 5-speed manual trans, and 4 wheel disc brakes - really a great, reliable car. So are the early Lexus 400's ok in the snow?   Posted in the wrong area earlier so let's try here.    Thanks, driveRight in NH.

Replying to: 2driveright (Nov 20, 2006 9:47 am) I would NEVER intentionally take my 1992 LS400 out in the snow when the roads are expected to be slippery. Were I to get "trapped" in such a situation the very first thing I would do is turn off the totally useless and occasionally unsafe traction control.   The 92 traction control system will INSTANTLY dethrottle, FULLY, the engine upon even any minor level of wheelspin/slip. THAT can lead to a few moments of "heart in throat" events, no way to move out of harms way until the ECU slowly releases the throttle.   Back when it was my primary driver I toyed with the idea of modifying it so the traction control defaulted into "off". As it was I just tried to remember to always turn it off whenever I started the engine.   And so I certainly would not buy one, nor advise anyone else to buy one, to be used specifically as a "winter car".   I survived many winters in central MT with only RWD vehicles and those were fine for that time. But today too many "better" options are available. And my advice would be to avoid, completely, any FWD or front torque biased AWD vehicle. Well, maybe the Acura RDX' SH-AWD if you can stand the "busiiness" of the dash clutter and ignore the owners manual edict about using tire chains only on the front.   Numerous back and forth phone calls to Acura engineering and in the end all they could tell me was that the statement in the manual might be a typo, they couldn't find any reason, support, for the statement.   Speaking as someone who's earliest driving experiences (1958), "training", (outside of farm tractors and mules) was on the ice and snow covered ramps of Pease AFB just outside Portsmouth NH.

Replying to: wwest (Nov 20, 2006 12:18 pm) This is exactly the kind of info I was looking for. I really appreciate your input.    The 91 LS400 that I'm considering doesn't have the traction control option so I won't have to think about it. As I said in my post my rear drive Cressida was great in the snow with snow tires on just the rear wheels. It might have been even better with snows on all 4.   I'm not paying a lot of money for the Lexus so I'm not worried about the adverse affects to the car - just how it might handle.
#8023 of 8360 93 Lexus LS 400 White Smoke from Exhaust by 93lexus Nov 24, 2006 (4:44 pm)
Hello! First time posting here so I am not sure what to expect. My problem is this, I bought my wife a 93 Lexus LS 400 about a year ago. It has roughly 200k miles on it, but is in great condition. We have not had any problems until recently. White smoke is coming out of the exhaust upon starting the car, it does not last for more than a minute or two, but is giving my wife concern, which means it is giving me concern. Does any one have any recommendations as to what the problem may be. Going to Lexus to pay their diagnosis & repair cost is out of the question, I only paid $3000 for the car and would hate to go beyond that since it is just a ride around town car.   Thank you for any help you may be able to provide.

Replying to: 93lexus (Nov 24, 2006 4:44 pm) Hope someone can help you. If no response on this forum, suggest you talk to a Lexus service rep and ask what he thinks might be the problem. Or talk to a local repair shop mechanic which specializes in Japanese cars. Good luck. Replies to this message: afiber2 (Nov 27, 2006 3:11 pm)

Replying to: rgsw (Nov 26, 2006 5:48 pm) Years ago I had a Firebird that had a lot of miles on it. It too smoked for a short period after starting. The problem was bad/worn valve stem seals which allowed oil to seep into the cylinder heads when the engine wasn't running and burn off when the engine was started creating the white smoke. If it is valve stem seals, they are not too expensive to replace however I would suspect your mechanic will want to do a complete valve job which is a little more costly.   Bill - Northwest IN - Shade tree mechanic in a previous life-

Replying to: 93lexus (Nov 24, 2006 4:44 pm) White smoke is either steam or coolant. Oil smoke is blue, fuel is black. The smoke is water or coolant boiling and then coming out the exhaust as vapor.   If the weather is cold, water will condense in the exhaust system after shutdown, then come out as steam on startup. This is OK. If you see the smoke after driving on the highway for an hour or it is an all-the-time event, you have a problem.   If you have a problem, most likely, at this age, it is a leaking head gasket. Possibly the cylinder head is cracked. Valve problems are possible but less likely. Keep track of how much coolant you add to keep it at the full mark. Obviously, this is expensive to fix.   Hope for the best.....
