Net 2MPG more with synthetic

[jasontoy]

I just changed my oil for the first time on my new 2006 at 5000 miles with the Dino oil in it. My first tank of gas with the new AMSOIL i got 38.9 hwy miles averaging 65 to 70 mph. Before the oil change at best I was getting 36.2.......less friction I guess means better mileage..... I got an extra 28 miles on one tank...........Do it

What was the price difference betweeen Dino and Amsoil?

[jasontoy]

Like 5 dollars a quart,but to me it is worth it because I won't change the oil for 15 thousand miles. Amsoil claims 25,000 miles or one year on both the oil and the filter. To me just the hastle of changing the oil every 5000 stinks. I put on 1000 miles a week so that would mean changing my oil every 5 weeks or some people change there oil every 3 thousand which would mean every 3 weeks! Think about it...long haul truckers drive from coast to coast in a week, they are not changing there oil every week....I think people that change there oil every 3000 miles have not much else going on there life to have the time to be changing there oil. That just my opinion and I am sure I will get a lot of heat for saying so...........

first oil change you say. the engine is getting broken in. More loose. I don't think it's the oil doing it

[jjminch]

I agree. Engines need to be broke in, so you can't really make any judgements for a while

[freakinbox]

like when I got my sr5 regular VERY dirty oil was in it. Drove for awhile with that. Then switched to mobile 1 synthetic and this time it's w/e oil changers used, petro canada stuff, meh all works the same lol. the biggest different in your gas milage for regular maintence would probably be the air filter. When I got the car the air filter was so dirty it started to blow holes through it lol horrible gas milage then.

Oh and tire psi is another huge one to watch!

All due respects to the 1'st post but I'm getting better that that with Dino (HWY) ...with only 3K on my 06 5-spd. I simply stay under 65 mph.
And around town I never really shift above 3000 RPM and when I can, shift from 1'st to 3'rd.

I changed out the OE oil at just over 1000 miles, and use Castrol Dino

what psi is the best?

[freakinbox]

what is on the tire or on the sticker in your door. I go by the tire, if you don't have enough air in the tire the car will become harder to handle

I concur. Even with periodic alignment checks, on all three sets of tyres I've had on my Corolla, when I set them at the 32 psi cold that the sticker recommends, each of the tyres wears on its outer edges, a telltale sign of underinflation. My 195/60R14 Bridgestone Potenza RE950s (as well as the 185/65R14 Potenza RE900s they replaced) allow a max cold pressure of 44 psi, so I usually set it at 40 psi or so. Fuel consumption improves, handling improves, and no noticeable degradation in ride quality or tracking on the highway. Same goes for the 29 psi recommended on my mum's '96 LS400... I keep her Turanza LS-H tyres at 40 psi cold, and we regularly get 26 mpg on highway trips. I keep my dad's F-350's tyres at about 70 psi, and can often squeeze over 20 mpg from the 7000+ lb truck.

How long have you been running 40 psi, I would have thought that would case overinflation and wear the center of the tyre. But it has been a long time since i've run tires that skinny and tall.

[freakinbox]

like I have said I had 51 in mine. Still has a bludge at the bottom but looked normal.

[punter]

I anything over 40psi wouldn't be good for handling, as at that pressure the the middle of the tyre would bulge out reducing the contact area with the road and thus reducing grip.
