First Oil Change

Wait until you get back to change the oil. Regularly changing the oil in your car is important for engine longevity, but it's not such an exacting process where you have to to it at exactly 5k. Especially if this is only an occasional thing.

 

Hmmm... IMO, since you're running on "new" oil that has gone through the break in period, I would probably change it. I know this is comparing apples to oranges, but on brand new motorcycle engines (typically 4 cylinder 4-strokes just like most cars, although they're designed to rev higher, higher compression ratios, but they are physically similar in many respects), typically recommend the first oil change half way through the break in period, and again at the end of the break in period. Reason being, supposedly, during the break in period, you may get more microscopic metal particles in your oil from parts "settling" in...

IMO, if you do it before the trip, you won't be worrying about it as much during the trip... :mrgreen:

 

if you encounter really hot weather I'd have it changed around the 5k mark. If the weather is cool and the temps are in the mid 70 I wouldn't bother changing it mid route. As the Prius engine spends a lot of it's time off or at very low power output an extra 1000 miles isn't going to do any harm. I wouldn't try for much over 6k though. If your really concerened I wouldn't hesitate to have it done before the trip. Remember to check your tire pressure before you leave and often during the trip. Probaby more important that the oil.

 

I both agree and disagree with the advice here. I see your oil change delima as more of an opportunity to upgrade oils. I doubt that an extra 1000 miles on the current oil will be such an issue. On the other hand if you change your oil before the trip you won't have to worry about it while on the trip. Peace of mind is a good reason to change your oil.

I'm not convinced that there is much break in activity on the engine that is occurring right now that may spoil the current oil more than normal engine operation would. These engines, and in fact all automotive engines are broken in at the factory. There should be no shavings or anything foreign in the engine at all, even brand new.

So, here is what I would do. Get the oil changed, but move up to synthetic. Also get a quality oil filter. Toyota filters are good, however there are a number of third party brands of filters which are better. I like Purolator PureOne. I combined that filter with Mobil1 5w30. I had my selling dealer do my most recent oil change out of convenience, however I provided him the oil and filter and let him do the work. He had no qualms about the materials I gave him.

Have fun on your trip.

 

I picked up our Prius on Wed. (6/1), the dealer wants me to come for a free oil change at 1500 miles. Then change it at intervals of 3000 to 5000 miles thereafter. They charge $25 for the oil change and $15 to rotate the tires.

 

[font=Comic Sans MS:547d9ded95]Good choice, but please don't be tempted by synthetic oil just yet. Some people report better MPG, but until all the metal parts in your ICE seat by the slight friction regular oil doesn't stop, you need to allow a little wear.

Another thing to watch for and watch out for is over filling. Three quarts is about right, or maybe 3[sup:547d9ded95]1[/sup:547d9ded95]/[sub:547d9ded95]2[/sub:547d9ded95] and take the other half quart with you. Overfull will be hard on the engine and lower MPG.[/font:547d9ded95]

 

Oil change. interesting subject. I had my changed today. The fire time i did not do it myself. It was amusing as the people at jiffylube tried to figure out how to run my car. I was laughing inside and worried at the same time. I don't like other people around my car. They seemed to have troubles finding out how to drive the car. I noticed the brake was on a lot.. forgot to shift? couldnt find P? the car would roll.. brake... roll.. brake.. lol. very amusing.

little did i know they reset the oil change, service, and filter in the computer trip info.... hmm.. cool. they know how to do something with this car. i think they overfilled though. I'll check it tomorrow morning since everything will be settled.
Even possibly overfilled, i'm getting 58.5mpg currently ( a lot of cruising on the highway )
