rustybrick Posted November 12, 2004 Share Posted November 12, 2004 I just got my SC430 2005 and it says that you should put premium gas in it. I did not buy the car, I am leasing it for 3.5 years. Do I really need to spend the extra 30 cents per gallon on premium or the car will work fine for the 3.5 years I own it? Thanks. Quote Link to comment Share on other sites More sharing options...
lovlex Posted November 12, 2004 Share Posted November 12, 2004 prem here is 16 cents more. if you mess up the engine, don't you still have to pay? i would use the prem to get the most performance. Quote Link to comment Share on other sites More sharing options...
sc_toy Posted November 12, 2004 Share Posted November 12, 2004 My god you've got an almost $100,000 car (CDN).... buy it the gas it REQUIRES. FWIW, the SC430 just won the JD P&A award for best initial quality with 44 problems per 100 cars. Industry average is 119... Aaron Quote Link to comment Share on other sites More sharing options...
Maximaboy1 Posted November 13, 2004 Share Posted November 13, 2004 I read that the SC4's have some kinda apparatus that "retimes the engine" when it detects knock...so if you put in 87, the engine changes in accordance with the "knock (if any!)" ....that's true for the SC400 at least. I honestly am not a believer in premium fuel...I had no difference in performance when I put premium in my SC400. I doubt there will be any engine problems if you use regular. Not to be longwinded, but why would an ES300/330, which uses the same engine as the camry, "require" premium when the camry equivalent engine does not?

ArmyofOne Posted November 13, 2004 Share Posted November 13, 2004 ik put premium in my 1990 ES250, surely you are not above putting int in you 05 SC430? if i had an 05 SC430, i would never put anything less than 93 octane in it...unless i absolutely had to, and then its only 91.

TMaxxTim Posted November 13, 2004 Share Posted November 13, 2004 The ES 300 DOES NOT require premium fuel. These engines require it in part because the compression rate is higher than in those engines resulting in higher performance. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted November 13, 2004 Share Posted November 13, 2004 moved to the general maintance section. This is up to you ,want it to be relable like a lexus then treat it as the service schedule and maintance says. This is talked about more than 30 times look at the other threads for the answer to your questions Quote Link to comment Share on other sites More sharing options...
Maximaboy1 Posted November 13, 2004 Share Posted November 13, 2004 I just think and have heard from some car magazines that you can put in regular, and if it doesn't cause any knock, then stick with it. Although, let's take a 20 gallon tank for example, the extra cost of $.30 for premium versus regular adds up to $6.00? You can justify the cost based on your budget, never let anyone just say "you drive a lexus, you can afford it, you should spring for it." I am very conservative with my money as you can probably tell, so IMO, just go for regular and see if it causes knock. However, most Lexus dealers and gasoline stations will just tell you to go for Premium fuel to support our wonderful little fuel makers.

bartkat Posted November 13, 2004 Share Posted November 13, 2004 You could save even more by skipping oil changes, filters, and other routine mantenance. When the tires go bald, don't change them either. No need to do any of that since you don't own the car. Quote Link to comment Share on other sites More sharing options...

rustybrick Posted November 13, 2004 Author Share Posted November 13, 2004 Premium it is. Just asking. Thanks for your feedback. :) Quote Link to comment Share on other sites More sharing options...
ArmyofOne Posted November 14, 2004 Share Posted November 14, 2004 Premium it is. Just asking. Thanks for your feedback. :) ← on th eSC430, the platform is based of the Toyota Soarer (JDM) IIRC (may not be now, because the design changed) but if it is, the base fuel over there is 91 octane, so it would make sense they require premium, also the CR makes a difference, as do engine materials.
