Mark@blueboys Posted October 2, 2009 Share Posted October 2, 2009 Hi, im sorry for going over old ground but i have just got my 350z and its in need of its service, im going to go to opie oils but am unsure what oil to use i have been told 5W40 or 5W30, surely only one is best suited to the engine? please advise, my car has done 50000 miles, if that makes any difference? Thanks! Quote Link to comment Share on other sites More sharing options...
Zednick666 Posted October 2, 2009 Share Posted October 2, 2009 Just got mine from Opie and you'll bag a nice 10% discount for being a member here... I'd go for the Silkolene Pro S 5w40, good high performance engine oil Quote Link to comment Share on other sites More sharing options...

jerry3167 Posted October 2, 2009 Share Posted October 2, 2009 Agreed, SILKOLENE PRO-S 5W 30 OR 5W 40 Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted October 2, 2009 Share Posted October 2, 2009 either viscosity will be fine. i went with 5w30 although i have royal purple race oil. opie are good and so is the silkolene. best get it now before the prices go up. Quote Link to comment Share on other sites More sharing options...
Beavis Posted October 3, 2009 Share Posted October 3, 2009 5w30 is what Nissan recommend. I use the Amsoil fully synthetic also from Opie Quote Link to comment Share on other sites More sharing options...

JoshC Posted August 31, 2012 Share Posted August 31, 2012 Sorry to cover old ground over and over again but just want to make sure, mine is due an oil change (93k) and I've seen a very good offer on Castrol GTX in Asda. What grades are reccomended as I've seen people suggest 5W 30 and 10w 40. Also, I'm guessing part synthetic? Quote Link to comment Share on other sites More sharing options...

Fully synth 5W30 Motul fully synth 5W30 in stock and good to go same/next day at £39.95 for 5 litres Oil filters and sump plug crush washers also good to go Drop me a PM if I can help you further Alex Quote Link to comment Share on other sites More sharing options...
