Drumster Posted March 7, 2011 Share Posted March 7, 2011 Engine is 180bhp on carbs. Raceline suggested Valvoline Synpower 10w/40, another BlatChatter has said he only uses semi-synthetic 10w/40. So, out of interest, what are other Zetec owners using.........? Link to comment Share on other sites More sharing options...
David Mirylees Posted March 7, 2011 Share Posted March 7, 2011 If it's an early type Zetec (Silver Top cam cover) then 5W30 must be used... Link to comment Share on other sites More sharing options...
CaterBram Posted March 7, 2011 Share Posted March 7, 2011 I Suspect chris has got a nice new shiny blacktop from Raceline 😬 If in the same place i'd go with the 10w/40, Using fully synthetic 0w40 motorsport in mine, but then mine is a series 2 silvertop which I use all year round.

Eugene Posted March 7, 2011 Share Posted March 7, 2011 I use Valvoline 10w/40 in my black top 210BHP - Chris at 7 Workshop recommends it 😬 Link to comment Share on other sites More sharing options...
Mick Day Posted March 7, 2011 Share Posted March 7, 2011 Nobody thought what API grade it requires? Is viscosity the only parameter? Link to comment Share on other sites More sharing options...
Doug Posted March 7, 2011 Share Posted March 7, 2011 Have a chat with the guys from Opie Oils. I use Silkolene PRO S 5W-40 Ester Synthetic Oil. Not cheap but very good. I look on the oil in my engine like it's life blood. Link to comment Share on other sites More sharing options...
Claire Voyant Posted March 7, 2011 Share Posted March 7, 2011 If it's a Raceline supplied engine and Raceline suggested Valvoline Synpower 10w/40 why are you just confused the issue here? Link to comment Share on other sites More sharing options...
Drumster Posted March 8, 2011 Author Share Posted March 8, 2011 As I said, "Out of interest"...... It would appear, for a variety of reasons, that everybody has their own opinions. In my old x/flow I was recommended to use Mobil 15w/50 and until the day it died (after over 50K miles of hard use) I always did and the internals were in very good condition as a result of many regular oil changes. However, I know of many other x/flows that are around that don't use Mobil 1 15w/50 and are still going strong.... Tricky business this oil lark....

Peter Mears Posted March 8, 2011 Share Posted March 8, 2011 So how many rep Zetecs blasted up and down the motorways with Castol or supermarket oil in them and didn't blow up? Some had little oil in them at all, I know as I had one and it still went to spain and back for years after I finished with it. Link to comment Share on other sites More sharing options...
Guy Lowe Posted March 8, 2011 Share Posted March 8, 2011 Quoting Aeroscreens: Raceline suggested Valvoline Synpower 10w/40 That's funny, 4 years ago when I fitted mine (199bhp), Raceline told me to use 10w/40 semi-synthetic , which I have done for 10K miles and it's fine. However I do change the oil each track day and at the beginning of the year, so the engine never does more than about 2k miles between oil changes. I was always lead to believe that the advantage of fully synthetic oil was longevity which in my case is not an issue. But someone will be along in a minute to tell me I am wrong (again) 😬 Link to comment Share on other sites More sharing options...
