My 1992 Acura legend is my baby with 176,000 miles and I'm really trying to see what I can get out of it for performance. I'm working on putting in a new air intake and a new exhaust system but before that, I'm ready for an oil change...My friend told me to switch over to synthetic oil to help clean out the engine and get it running better. He told me to change the oil with synthetic for like 3 oil changes then continue with a synthetic blend. I'm willing to pay the money for it but should I switch over to full synthetic? If not, what should I use for performance?Thanks for your help! It's really appreciated!Well thanks for your answers...Yes it is a 92 and yes it does have 176k miles on it but its an engine that will last another 100k to 150k if taken care of well. The body is still in good condition so why not fix it up? I'm not asking for a racing beast or anything, just something where I can punch it and it has a really good kick to it...ALSO oil does make a huge difference in a car's performance...I'll stick with 5w-30 mobile 1

Usually 5W30 is good.Some companies make an oil for higher mileage cars.Synthetic isn't always good

exactly what it calls for- 5w30tricking out a car w/ 176K on it is just asking for trouble, even if it's an Acura. Synthetics won't make it run better. How would oil make it run better? Make it slippery? If it were that easy, all of the auto manufacturers would be using it.

dont use synthetic oil because the engine have high milage and synthetic oil are way too think and will cause a oil leak. if it was my car i would just keep using the regular 10-30w oil or 5w-30w.

you have a high mileage car and NOW want to trick it up...hahahahahaha...funny...manual says 5W30....use it or lose the engine.

stick with 5/30any brand will be finesynthetic is a waste of moneyoh that intake and exhaust is also a big waste of money toois a 92 with 170k

With high mileage on my car I use Havoline 10W-40.
