Justthejedi Posted October 1, 2013 Posted October 1, 2013 does anybody know if this oil is any good? It's semi-synthetic and was put in my car 3000 miles ago (before I purchased the car). Cheers Justin Quote
Neilp Posted October 1, 2013 Posted October 1, 2013 Car should have 5w30 fully synthetic in it. I'd get it removed ASAP and changed to a premium fully synthetic Quote
Arran Posted October 1, 2013 Posted October 1, 2013 Wrong grade oil and it needs to be fully synthetic and its not that great oil either You need 5w30 fully synthetic Quote
Justthejedi Posted October 1, 2013 Author Posted October 1, 2013 cheers guys, I'll get it drained and replaced with the correct oil. Quote
Tricky-Ricky Posted October 1, 2013 Posted October 1, 2013 Personally I wouldn't worry, mine was quite happy on Shell helix 10w40 nothing wrong with a semi synthetic, the jump from w30 to w40 is not great, and TBH with Nissan's engine tolerances it made virtually no difference to oil pressure, maybe 1-2 psi. Quote
Arran Posted October 1, 2013 Posted October 1, 2013 10w40 semi is completely the wrong oil though so there is cause for concern imo Quote
Ekona Posted October 1, 2013 Posted October 1, 2013 Is it the right oil? No. Is it going to make your engine collapse? No. Long term it won't do it any favours and you'll be losing power, but it's better than no oil at all. I'd replace it sooner rather than later and I wouldn't go tracking it, but to use it normally won't hurt too much. Quote
rtbiscuit Posted October 1, 2013 Posted October 1, 2013 That grade and viscosity will make no difference. It just won't be as effective for as long as a fully synthetic. Changing it would be a good idea but I wouldn't be panicked. Cheaper oil degrades under heat cycles quicker but its still lubricating the engine. So as long as the engine has time to warm up before spirited driving it will be fine. Do a mini service and put fresh oil and filter in. There are some good semi's out there, so it doesn't have to be fully synthetic. And the thinner viscosity will make it easier for the engine to crank over in the winter. Quote
Level 7 Boss Posted October 16, 2013 Posted October 16, 2013 Crap I've just ordered the below, recommended by Opie. Fuchs titan. 5w-40. Hopefully it's ok? www.opieoils.co.uk/p-60166-fuchs-titan-gt1-xtl-5w-40-synthetic-engine-oil-bmw-mercedes-porsche-vw-more.aspx Quote
Paddy78 Posted October 16, 2013 Posted October 16, 2013 I thought some people ran 10w40 to help engine ware on older cars or ones which were burning a bit? I was going to switch to 10w40 at my next service... I might rethink! Quote
Neilp Posted October 16, 2013 Posted October 16, 2013 I don't understand why people switch from what the manufacturer recommends???? They recommend for a reason to suit where the car is going to be used(in terms of temps etc) and to protect the life of the engine! Quote
Streetwise Hercules Posted October 24, 2013 Posted October 24, 2013 They do Paddy. My GT4 is burning about 3/4 of a litre every 1000 miles and Japex have advised me to try the 10w40 from now on. I'm happy to follow their advice. Some of the responses on this thread are laughable. Quote

NeilMH Posted October 24, 2013 Posted October 24, 2013 As NeilP said earlier - which responses are laughable and why? 1 Quote
Arran Posted October 24, 2013 Posted October 24, 2013 Not sure where laughable responses are myself, care to share? Quote
Streetwise Hercules Posted October 24, 2013 Posted October 24, 2013 Reading back 'laughable' is a bit strong, but the tone of urgency in some of the replies is a bit much and some of the statements of 'fact' do differ to advice given by professionals who specialise in these cars. It's fine, it'll be fine and it's very similar to what I'm about to put in a car I like to take good care of. Quote

It's worth reading this: http://www.350z-uk.com/topic/71469-the-advantages-of-synthetic-oils-over-mineral-oils/ To a lesser degree, the points covered in the above would apply to semi- synthetics also. The other point is that when it is not clear what use the car is going to be to, it pays for members to be cautious with oil recommendations. Quote
Jez @ H-Dev Posted October 24, 2013 Posted October 24, 2013 (edited) Nissan actually say that you can use 5w/30, 10w30 and 10w40. 5w30 is prefered but the others are fine so long as ambient temps are above -18deg C. Semi synth is fine too, for road driving. Synthetic oils are better at coping with higher temps and they maintain their lubrication properties for longer. So the oil justthejedi has shouldn't cause any probs at all. Edited October 24, 2013 by Jez Quote

The other point is that when it is not clear what use the car is going to be to, it pays for members to be cautious with oil recommendations. Extract from a European Court judgement: "Synthetic is a marketing term and its up to the marketer of the oil to define what synthetic is." Therefor, any oil that is subjected to any unconventional practice can be labelled synthetic.Most "fully synthetic"oils have as much as 20% petroleum product added as a carrier oil for the additives, so it is labelled as "fully synthetic" when it is not. Why,if "fully synthetic" is so good,are the change intervals exactly the same as mineral oils? It seemed to me that some of the answers given to Justin may have scared him into thinking it would wreck his engine, when,as Jezz said, it won't do any harm at all.

NeilMH Posted October 25, 2013 Posted October 25, 2013 When all is said and done I guess each owner makes their own decisions for their own reasons. One thing I have always done with my performance cars is to put in the best oil I can.... I can't see much downside to that other than an element of additional cost. Quote
maddog1982 Posted October 25, 2013 Posted October 25, 2013 What are the best brands of oil these days? Quote
Ekona Posted October 25, 2013 Posted October 25, 2013 The expensive ones Don't know why I'm laughing, that's true really. Motul, Mobil 1, Fuchs, and there's another one that's been mentioned on here before too that a lot of people in the know are using these days too but the name escapes me now. Which is irritating, and it's probably the one to go for as well. Quote
