Gulf Western SYN-X 5000 (10W40)

This engine oil is very good value for money! – Brought two 5-litre bottles while they were on special from Repco for a total of $60.00. Was a bit reluctant and sceptical first...I have been using either Valvoline Synpower or Shell Helix HX8 for the last five years, but since I've got two old cars, I thought I'll just give Gulf Western a try and see how things go. Result: It was and is right up there with either Valvoline Synpower or Shell HX8. Had the oil changes done three months ago....I checked the oil quality and quantity every fortnight...oil stayed clean and still at the right level. No problems so far. Looks like Gulf Western syn-x 5000 is performing well. Would buy it again, yes!

Excellent quality at great prices – This was recommended to me by a fellow professional mechanic and have had great results. It may clean up an engine after previous poor quality oils have left sludge. This may cause the oil to discolour at the first time use. Will continue to put it in my fleet including the newest acquisition, a Land Rover Series 3, V8.

Cheap and nasty oil – Own a 2007 Hyundai Elantra and was due for 90000k service, Hyundai were miles too dear so went back to our old mechanic. Oil used was Western Oil and shortly after noticed the motor was noisy on start up. Dipped oil and it was already dark and starting to stink and it had burned onto the dipstick even though the level was ok. This was at 93000k...ONLY 3000K AFTER SERVICE!! Drained oil and cleaned dipstick and replaced with Castrol and engine is again smooth and not noisy on startup and oil is lasting longer with no burning on dipstick. Won't ever go near Western Oil or this local mechanic again. You are charged the same for this garbage oil as you are for a good oil so am of the opinion it's obviously a cheap blended oil for workshops that they use to maximise their profits, Contacted Western Oil in Shepparton, being the local distributor, at the time and never heard back from them.
