Any thoughts or advise about switching to synthetic oil on a gsr with 124K. It's had castrol 5w-30 for most of it's life.

 

Absolutely The Sooner You Switch To Synthetic The Better, I Use Mobil 1 5w-30

SuperSyn Fully Synthetic, I Switched At 115k Mi. Within 100mi Of Buying It From

The Original Owner, The Car Has Just Been Feeling Better And Better

Mobil1 SuperSyn 5w-30

SWITCH

 

Thanks, had it ready to switch and a couple of guys said it may be a problem with the vtec. I couldn't understand why it would.

 

the only thing to watch out for since you already hav 124K on the car, if it leaks or burns at all now, when you swtich to the synthetic it will be worse. my buddy found that out real quick

 

I dont see the point in switching to synthetic at this point of the engines life. A switch to synthetic could possibly bring some leaks to the surface. A lot of people with agree with this and a lot will disagree. But why risk it?

 

Motor's really tight and no leaks. If it ain't broke don't fix it makes sense some times. It's hard to get an answer if it's worth it when there's 124k on the clock. It costs 3x and lasts only twice as long, so it's no cheaper.

 

I Change My Mobil1 5w-30 SuperSyn At 3000mi. Regardless Of How Long It Lasts,

Its Only $45 Every 3 Months, If You Can't Afford $.50 A Day Than Dont Drive!,

You Should Be Walking!

i heard this was bad to do...ask typerman he said switching will expletive up your valves or some ****

Yea more info please

 

this is my understanding...if your car has been using regular oil for 124K, as dumb as this sounds, your seals and such are used to it. by switching to synthetic which is thinner than standard oil, it can slip past for example 124K mile valve seals a lot easier than regular oil, therefore your car will burn oil.

 

And if your car doesnt start to burn(lose) oil then this doesnt apply to you ? ??

Bump for more info

 

ask typerman he's hte expert

From my own experience...DONT DO IT! I bought my last car (JDM Si-VTEC) with 86k miles on it, the prevoius owner used regular mineral 10w40 for the previous 40k miles. I used the same oill up until 95k miles and then changed to mobil1 0w30 and when the car reached 105k miles it was burning more oil than gas. I was using approx 7 litres between 4k mile services. I had to get the whole thing rebuilt, oil and compression rings were shot to pieces. Before switching to full synth. oil i was topping up by maybe 0.5-0.75 litres between services. My mechanic who rebuilt the engine reckoned that the synthetic oil cleared built up sludge left by the mineral oil and exposed worn rings which dramatically increased oil consumption. You could look at that two ways,
1. It'll show weak gaskets/rings/seals and you may need a rebuild (which may be ok if you plan keeping the car for a while) or
2. If you had just continued using regular oil, the engine would have been fine, and you could have continued driving it for whatever lenght of time without having to rebuild it and so cost way less.

I say switch back to your old oil before its too late

 

i wouldn't really recommend it at 124k... when i switched over to fully synthetic oil.. i started to have leaks everywhere! had to replace cam seals, crank seal, valve cover gasket... etc. especially when you have a GSR.. it'd probably burn more oil than mines. but hey.. it's your car and your choice!

 

i wouldnt do it. it might cause leak and oil burn.

i'd stick with whatever you are using now. (castrol GTX FTW!!!)

 

Alright I found in the records for my car that they were useing Castrol GTX for the past few years ... I didnt know this and started to use Mobil 1 syn , Ive noticed lately alot of engine sound .. like my valves (im guessing) I thought maybe I needed an oil change (ahead of time) and went to get it done ... Got it switched the old oil was VERYY dirty so i had them do one of thoes engine clean things (haha) and put in more mobil 1 syn .. The sound remains ..

It is not thinner, it is sliprier.

As i have stated in the past, a mobil rep talked us (the company i work for, all crew techs) and said synthetic can cause leaks. The reason it can cause leaks is because it has the additional XX% of detergents in the oil which clean up EVERYTHING inside the engine. All sludge, varnish, deposits will get cleaned away with time because of the detergents. SO, if your engine was well taken care of, and the basic oil was changed regularly every 3 months, you "theoretically" should be fine...as in hopefully no leaks. I have seen some oil leave behind a "film of ****" as i call it even if you change it 3 months...pennzoil from what i have seen.

I switched to fullsynthetic when i purchased my gsr with 116k on the clock. The only thing that is starting to leak is the oil pan gasket, but barely at all. I guess its a crap shoot since you cant really tell how well the previous owner REALLY took care of the vehicle.

 

don't do it times lost count even if you don't have leaks now they could show up in higher mileage cars when you use synthetic.

 

I started using synthetic in my integra with about 105k simply because I had no idea what kind of oil the previous owner used. How much oil did I burn in between 4k oil changes? less than a quart. And I beat the living **** out of the car for the beginning half of the 40k I put on it. I just put mobil1 in my civic with 85k; once again I just bought it from a dealership; the oil could be 85k old for all I know. I guess time will tell how the little d16 does, I hope it doesnt start leaking because it in great shape right now.

 

i'm thinking of putting royal purple racing 21 in my motor b18b 294,000km on it, is this gonna be a bad thing to do... it doesn't burn oil right now...but will it?

 

I can't believe the nonsense some people are posting here. "I heard blah blah blah", ridiculous nonsense.

If you want the benefits of synthetic oil - greater resistance to breakdown when hot, better flow characteristics when cold - then sure, go ahead and switch, whenever you want.

If your car leaks with synthetic, it's because there was something wrong with it that needed fixing anyway. Just like it says on the Mobil 1 website:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Mobil 1 website &raquo;</TD></TR><TR><TD CLASS="quote">Myth: Mobil 1 will leak out of the seals of older cars.

Reality: Mobil 1 does not cause leaks. In fact, new Mobil 1 was tested in dozens of industry standard and original equipment manufacturers (OEMs) tests to prove its seal performance. It is fully compatible with the elastomeric materials from which all automotive seals and gaskets are made. If an older engine is in good condition and does not have oil leaks, Mobil 1 provides the same advantages as when used in a new engine. ExxonMobil recommends taking measures to repair the leaks, then using Mobil 1. ExxonMobil also recommends following the automobile manufacturer's manual for the proper oil to use.</TD></TR></TABLE>

Sheesh...
