My engine has been receiving sythetic for the last 35,000 miles and maybe longer, depending on the history of the motor. Only problem is that it burns oil, not too much, but enough to get on my nerves, its getting rediculously expensive to be buying oil all the time just to burn up, and I change the oil EVERY 3,000 miles, so I want to go back to regular oil.

I was just wondering if it will be OK, or should I do something else to it?

 

How bout you put synthetic in.. since its not THAT much more.. and then you get your car fixed so that it stops burning oil.. because im sure its a problem that CAN be fixed!

Edit: Im sure its ok.. but i wouldnt put crappy oil in an engine with high miles.. i want mine to last as long as possible.. Synthetic only for me please!!

My compression is great, and synthetic IS that much more, it costs around $5 quart, and I have to add more at least once a week, due to the amount of driving, when I say "high mileage" engine, I'm not really sure, its a 94 US spec motor, but I have no way of telling how many miles were on it before, except that I have added 35,000.

And I wouldn't use some cheap-o brand x oil, I would use some name brand, just regular oil.

 

Sounds good.. its your car man.. Do what you wanna do.. Most of the people on here like to baby their cars though(including me) so we will all pretty much say stick with synthetic.. but im sure non synthetic wont hurt anything! Good luck with the oil prob as well!

 

how about you fix the ******* problem of burning oil?

EDIT: that was kinda harsh... but a quart a week!? god damn! what do you mean that's not a lot?!

if your compression is good, and you're using up a lot of oil, you may want to think about a thicker weight.

 

That... or maybe by some freak chance, your running rich? How do your sparkplugs look? If your eating THAT much oil then you really have a problem. Look into fixing your engine and not just changing oil.

 

there is nothing wrong with changin to synthetic. i would recommend doing that. go with 10w-30

 

I had the same problem, I have a 94 GSR with 110k. I got one free Pennzoil synthetic oil change and notice I burn almost a whole qt. by the time I reach 3000 miles. I was like WTF? My compression and leak down test were fine, clueless as to what happen. I'm not gonig to spend $5 extra every oil change. And judging from what I have seen on this board, it can get worst, even with cars that are new/fairly new running synthetic oil.

Went back to regular Castrol GTX and it's been like 2k miles, and hasn't burn a drop. Do a search, a lot of people running Mobil 1 have notice it "burns up quick"

i just bought a 95 ls teg with 140,000 and im due for an oil change. so u guys recomend that i use synthetic 10w-30 right? ne brand in particular?

 

do you have an oil leak, or does your car just burn oil? My car used to have a pretty fat cam seal leak..i had to always have an extra court on hand, buts its all fixed now. No more leak like the other guy said...run synthetic and get your car fixed

 

I had a similar problem too. I was running mobil1 5w30 and noticed that i was eating up oil pretty fast... like a quart a week. I checked my spark plugs and didn't notice anything unusual and i even took it a mechanic to have it checked for a blow by problem. on a last resort i changed to 10w30 and now the problem seemed to have disappeared.

 

That's easier said than done. A buddy of mine w/ a '95 GSR that had over 120k miles was adding at least a quart per week to his engine. His car was still strong and ran great, but short of a complete engine tear down, there was nothing he could do. Adding a quart or so of oil every week is a reasonable option for those who don't have the $$$ to tear their motor apart.

 

As mentioned this has been a common discussion lately (mainly on the Type-R forum). A lot of people lately have commented on how their car has been using or "burning" synthetic oil and they have commented that they have switched to a non-synthetic oil and their cars have stopped using oil. If you have performed a compression and leak down test and the results where good, I would recommend switching to a non-synthetic oil.

 

I think Bror Jace has recommended Valvoline Max Life as an excellent conventional oil choice on a number of occasions. My old car had some problems both w/ leaking and burning oil. You could be leaking oil past the valve guide seals when the car sits for awhile, which then gets burned up when you start the car. Do you notice a slight puff of smoke out of the tailpipe when you first start the car in the morning? If so then it is definitely the valve guide seals. Some of the other seals in my old car were leaking, as well, like the cam seals, the front crank seal, etc. Look into those as another source of oil loss.

Lucky for me my car burns no oil, and the only leak I get is from the plastic cam plug, and I have 112K miles, been running synthetic the past 22K miles. However I may switch to Valvoline Max Life soon, since I will be returning to school in MS and I can't get Mobil1 as cheap as I can get it here in Nashville ($3.60 for individual quart bottles at Wal-Mart).

 

I used to run mobil 1 exclusively in my integra, then I ran GTX one time because I was a bit short on cash. Funny, the car consumed mobil 1 at the rate of about 3/4 of a quart per 3000miles. When running GTX, the oil consumption is nil. It is just a known fact that bseries motors use a little oil when run hard. Even low mileage type Rs have to deal with oil consumption. However, using conventional oil as opposed to synthetic seems to decrease the oil consumption drastically. The majority of people on the ITR forum run non-synthetic and there is a reason for this. BTW, the car has 121,000 on it and is exceptionally strong.

 

You! I see you driving sometimes.. i'm never driving my car when i see you though .. i wanna see and compare cars!! MUAH! Unless there are other 4-door white GSRs running around the dublin/worth area!?

 

could be your valve guide seals

 

To replace the cam seal, do I have to take the cams out? If I end up doing that, will I have to re-adjust the valves?

 

hell yeah, small world..............

 

I am burning a quart a week or so....but it's been more than that at times...depending on how hard i drive. Rings are pretty much cooked and I'm hopefully gonna get a swap soon cause I'm tired to spending $$ on oil..besides...I don't know anyone else with a teg that smokes like mine. It's getting embarassing, not to mention I'm really slow due to loss of compression.(bad rings)
