Hi,
I stumbled on this forum an I am amazed at how knowledgeable you guys are about oil. You were the independent opinion I was looking for and I hope you can help.
I own a small engineering company in the UK that produces parts for MX5s / Miatas. One of our biggest sellers are our turbo kits.
We have recently expanded and taken on a full-time mechanic as we realised there was a market for servicing MX5s and also fitting our own turbo conversions.
We really want to stock a single brand oil in the shop and I am struggling to get some independent views.
The engines we work on are 1600 and 1800cc gasoline IL4s. Naturally aspirated they have an output of 70-80 bhp per litre and when we turbo them we usually run 130-140 bhp per litre.
The stock oil is a 10w-40.
I have been using Castrol edge 0w-40 in all cars. However, when buying it in small quantities I have noticed the specs are slightly different on the back? One says A3 / B3 on the front, the other does not but says C3 in the blurb on the back? Are they the same oil?
Now I want to buy it buy the drum load I am looking around. Should I stick with Castrol edge or is there anything else worth using? What about something like the fully synth from Petronas?
Thanks in advance,
Doug.
