Argh, Motul Turbolight 4100, Wtf?

[fighterjet33]

Today I jis purchased Motul Turbolight 4100 after a few mates recommended it, as soon as started my baby was the whole engine began to shudder, it settled down after reaching temp (which is at exactly half, same as previous oil) however when driving under 2.5 - 2K revs would still shudder, my presssure has dropped also to below 4, and wait for it, turbo doesnt boot in at all, jis feels gutless and runs ruff as rocks. What would be the best thing for me to do to fix this?

Thankyou.

which weight did you use? What oil was previously in the car? Are they the same weight?

How many litre did you put in?

[INVRTD]

ay mate, i noticed when i used motul my pressure was always really low, 2-4, so yeah not the only one out there, it used to sit on 6-8 with castrol edge

best way to fix, dump oil, put different brand in, if problems persiste see your mechanic asap

also. turbo light 4100 arn't exactly a good oil to use. It is semi synthetic.

If your budget allows, go royal purple, mobil 1 supersyn or motul 300v.

[poobah]

arhh dam just bought some turbo light today!

[Kujotk]

did you accidentally put cooking oil in it???? depending on modds and all that but no motor oil should do that..... change the oil and see what happens.... other than that it does seem to have similar symptons to a spark problem with the info you gave.... i'd check that if the problem doesnt go away

Some experts on oil in this thread i see....

There is nothing wrong with turbolight, and as for being a semi-synthetic, most oils are actually semi-synthetic, even if it says "Synthetic" on the oil, it doesn't mean it is 100% synethetic. But thats another topic. Back to the original problem.

What your describing has nothing to do with the properties/brand of the oil, its a 10W40 for the record. What else was done to the car at the same time as the oil? Spark plugs changed?

[Kinks]

yep the oil couldn't possibly cause that on its own unless someone mixed it 50/50 with water!

turbolight is fine to run in a skyline, a fully synthetic oil would be better though.

ive used it before and no probs. true that oil pressure is lower but i cant see it being the cause of your problem though. did you do anything else when you changed your oil like sparks, fuel filter and stuff. they would more likely be the culprit than the oil in my opinion.

Yea.. thats y I recommended 300v and mobile 1 supersyn, since they are 100% synthetic. i.e. group 4, 5 synthetic base. Not sure about royal purple thou. 4100 is probabaly group 3 and group 1 oil mixed together, fine if you use it in camery, but no way in hell i'll put that in my skyline.

did you spill some into the coilpack area?? i second that no oil can do that on its own.. only if it gets in somewhere its not meant to, or its soo thin that its getting into the cylinders..

maybe your turbo seals are kapoot.. thinner oil seeping in there, boost seeping out etc. mine did this when my seals went.

and for the record... i use repsol competion elite... never had a problem.. $68 for 5L.

Yea unfortunately I filling up the oil was the only thing i did to it at that point, so kinda makes me think that maybe my turbo seals have blown or something >.< however i didnt drain the previous oil remainders out, wouldn't have been much but yea should i have done this? yeah it seemed to want the whole 2 litres of the motul and well i will have to drain the motul out n e way, is the bolt hard to get too? i fear i may to jack it up

[(B1) MR_fanny]

it should take about 3.8-4.2L of oil. when you mean remainders, you did drain the old oil out first yeah? Your asking if its hard to get to the bolt which implies that you didnt change the oil at all, you just filled 2L of motul in with the old oil. Thats a lot of oil to pack in. when i bought my turbolight it came in more than a 2L bottle. Did you change the oil filter too?

sounds like you didnt do a proper oil or a service for that matter to me...thats how I'm seeing it from what you've said.

[Cassbo]

The sump plug bolt isn't at all hard to get to. I can get at it without jacking my car up (stock ride hight). If your car is lower you might need to jack it up, but it would still be easy to get at.

Nothing wrong with 4100.

I have done many oil changes with it. Pulled engine down for a rebuild and the engine was in perfect condition. As long as you do an oil change every 5000km its perfectly fine.

[PUDZ 32R]

there is no engine oil on the planet that can cause ur motor to run like that. unless u did something wrong. did you even drain the old oil completely includint the 500ml or so that is in the oil filter. if u are going to do an oil change u need to do it properly or there is no point in doing it. i usually change my oil every 5000km and have had no worries. i even put a very heavy 25W-60 in one day to see how the enging would behave. nothing happened but the oil pressure was higher.. it sounds to me like u just topped up the oil that was alreeady in there with new oil. probably massivley overfilled the sump causing windage. where the crankshaft hits the oil and churns it up. if u drained the oil and only put in 2L ur in trouble.. put more in ASAP and check ur dipstick. that is what it is there for.

ummmm so you had all your oil in the car (4.5-5L) and then added 2L of Turbolight into it.........?

Where is it meant to sit? mines sitting between 3-4 but seems fine? now im confused!

Oh dear

[fighterjet33]

Thanks for all the help so far guys, unfortunately i have been a ford (cough cough) person my whole life until now so im not too mechanically familiar with my baby >.< having serviced at the mechos, does sound like i have overfilled it a bit, obviously my dipstick is accurate, my pressure had been sitting low for a while and it sounded a lil rough, problem is obviously with something else and i may have jis made a new one yay.

I noticed an oil leak dripping from near edge of the cooler this morning, so kind makes me think yea its overfilled.

PUDZ you were saying .. "it sounds to me like u just topped up the oil that was alreeady in there with new oil. probably massivley overfilled the sump causing windage. where the crankshaft hits the oil and churns it up".... windage does this cause a bit of a shudder at times if this is what u are refferring too?
