At 19,000 miles, what would ALL the benefits be of changing to synthetic oil for my 2.4L? I mean, I know some, but I'm not sure if I know everything about synthetic oil. And should I use Lucas Synthetic Oil Stabilizer? A couple people have suggested that to me. Thanks.

 

i use castrol syntech in my RT, and it makes a noticable difference...

 

I have a 2002 LXi and switched over to Royal Purple synthetic oil and I went from 23 mpg city / 26 mpg highway to 26/30. It took awhile for this to happen, but it did. I would strongly suggest switching over to synthetic of some type.

 

My brother runs Mobile 1 synth in his NSX and keeps telling me to do it to but at 80K miles will it really do me any good? he also has about 80K on his NSX but hes a performance nut so thats why I know he uses it.

 

So do you like the Syntec to Mobil 1?? I've always used Mobil 1 but am open for new ideas. Why the Castrol?? Oh and It's almost time for my first oil change. Synthetic?? Do ya think??

 

I may have posted worng in reply, Im sorry I thought the name of the oil was MOBILE 1 SYNTHETIC that my brother uses maby its not MOBILE "1" It made by MOBILE and its the SYNTHETIC that he does use.

I havent used synthetis at all in any of my cars. Its expensive and if you got to spend 5 bucks a quart only to dump it after 3k miles as I do wih regular 10W30 then I figure Ill just use conventional oil and save money. Weather it really will reduce engine ware so late in my cars may not even be an issue at this point.

 

sxtnny...i used syntech because that was what we had in the shop for the drag car. i honestly dont remember what kind of synthetic i put in when i changed it last time...

i know that it was castrol.

 

How is it possible to gain a lot of mileage per gallon by changing to synthetic? That doesn't sound possible.

 

i wouldnt you will gain ALOT of MPG...but may likely notice a difference.

 

Ok. Well one guy I know of said he gained 5% better economy, but it happened over a good chunk of time, and that change could happen for a variety of reasons not just the synthetic oil. One guy earlier in this post said his gains were almost 16% (from 26hwy to 30hwy). That just kind of shocked me. That's like going from winter driving to summer driving.
