Im contemplating switching my 2006 accent over to synthetic at its 45,000 oil change. I have been changing the pennzoil 5-20/5-30 every 3750K miles (half of the manufacturers recommended 7500 interval). It's mainly a commuter, about 80 miles of freeway per day. I would like to be able to go the whole 7500mi between changes. What 5-20/30 would be a good synthetic for the hot summer and 7500 mi intervals?
 
PP, Amsoil or Mobil 1 would all be great choices. Truthfuly almost any synthetic should be able to go 7500 miles without any problem.
 
Regular API SM 5-20 or 5-30 is fine for 7500 intervals on that vehicle driven in that manner. I run over 10000 mile intervals with PP in a vehicle that is recommended to go 5000 between changes. Stellar UOA's.

Seriously, if you are only going to go 7500, don't spend the money on "synthetics".
 
Get a 5 gallon container of Mobil 1 at Walmart, maybe they have PP also, cannot remember. I would get a decent filter to go the 7500 miles, as in Mobil 1 filter or Amsoil Ea filter. Or a Supertech and change it half way through.

Amsoil is also excellent synthetic oil also, just a little harder to get and more expensive.

5 quart you mean? And why bother changing the filter?
 
7500mi OCI in a commuter vehicle? Why the need for synthetics? Get 5quarts of a quality dino like valvoline or pennzoil for $9 and run it 7500mi. Do a UOA at 5k if you can't wait to do one at 7500.

Synthetic would really be overkill for you.
 
Thanks a million. As Titan mentioned I have debated the "need" for a synthetic oil in that little car which is why Ive gone 45000mi without it thus far. I'll probably give it a try just for the "peace of mind".
 
I recommend Amsoil or PP.

Get a good oil filter also, like a Wix, NAPA Gold, PureOne or the best Amsoil EAO.

For 7500 miles? Any oil and just about any filter. Really: do a UOA and prove it to yourself so you can start spending the extra money on something worthwhile.
 
asking what kind of oil to use on BITOG is like asking a group of deadheads what was the best grateful dead show ever.

Like most have said, any sm dino will more than likely get you safely to 7500 miles. A pure one filter, wix, napa etc will get you 7500 miles also pretty easily.

If you wanted to do synthetic, and while I agree amsoil is probably one of the best right now, any readily available syn at walmart or auto parts store will get you 7500 easily. A syn blend would get you there no problems.

You can even make you own syn blend. I have used 3 qrts pennzoil 5W30 and 1.5 qrts pennzoil platinum. You can do half and half or whatever you wanted to do. Just an idea
 
That car has a very small sump. It only holds a total capacity of 3.5 quarts. And thats with a filter. My wife has one. Having a smaller amount of oil to lubricate the entire engine, means that less has to do more.
We use Mobil1 5w30 in ours. With a Mobil1 filter. Lots of short trips in it as well. I change the oil out at around 5000 miles.

Next change I am going to try Valvoline Synpower
only because I got it at a buy one get one free sale. And a Purolator Pure One filter. I like the purolator filters as well as the Mobil1. I think the Pure One filters are just as good as the Mobil1 filters too.

The valvoline synpower is decent. I feel (just personal opinion) that the M1 would do better for 1 yr intervals depending on the miles driven. I use pure ones myself. Although I did get an M1 filter when I got 5 quarts of GC 0W30 with the deal autozone had going on.

That has got to be one of the best analogies I have ever seen here.

My Corolla has a sump of 3.8 quarts incl filter. Highway about 80% of the time with VERY short (less than 2 miles ROUND TRIP with a hour between) for the other 20%.

Here is a 5.1k UOA: 5.1k mile OCI

Here is a 5.8k UOA: (notice the TBN) 5.8k OCI

Small sump. 7500 miles with your engine and commute. Any SM oil will do.

SPEND the $25 for the UOA once and then SAVE the $10-$15 EVERY oil change using conventional over Syn.

Money NOT spent is money saved. Changing ANY SYN less than 7-10k is a waste unless its force fed or the manual states different.

My 3 cents.

I don't mind changing the wifes synthetic in her Hyundai every 5000 miles. It can take her 6-7 months to rack it up. I think that a quality oil change twice a year is not too much to do. And I feel its money well spent. $50-$60/year on oil maint. is OK with me.
Especially when I can find it on sale.
3.5 qt sump is very small, and the filter on these cars is tiny as well.
I get free oil changes for life on my Mazda that I bought new. Now that was a major selling point.
Oh yeah, and if the engine ever blows while I own it, no matter the miles, its also guaranteed for life.
