BONGO ENGINE OIL

Post by skyfever » Wed Jul 11, 2007 10:42 pm

What is recommended as the appropriate/best oil to use in the Bongo TD engine - does it matter what type,grade, make is used?

I use a semi synthetic 10/40 weight oil, changed with filter every 5000 miles,or yearly,whichever is sooner.

I think that 10/30 oil is the type that you are supposed to use,but apparently its not a good move if your bongo engine has a few miles behind it...

Put whatever you want in between 5W30 and 10W40 but use good stuff. Decent oil is very cheap insurance.

I go for 5W30 (original spec I think).

Hi, I use a semi synthetic 5 / 30 Diesel oil and do an oil / filter change every 6 months / 3000 miles but then again I only do 6000 miles a year.

I used Magnatec oil 6000 miles ago, and it still looks ok now, but thinking of changing soon :-k

Being only 4.5 litre a tub you would need two :cry:

The last time i visited Costco, they were selling two 4.5 litre tubs for £29.95... I think its almost that price for ONE tub from halfrauds... :shock:

Is my Halfords 5/30 not good stuff then. I'd hoped the contents were kosher but cheaper (£21 for 5l) cos you werent paying for a branded bottle. I dont have Costco etc. near me 8)

OIL? I use the stuff they sell in Costco for diesels. 20 litres around £25, I change the filter twice a year and the oil every 3000km as I burn Veg Oil. But if you Google API then you will begin to understand the codes on the oil and can see that £26 for 4.5 litres aint much different to £5 for 4.5 litres. Particularly in a slow revving diesel.

The recommended oil change is so regular that buying expensive oil just aint worth it!

Is the recommended change every 3,000miles due to the oil's available 10 years ago? while Magnetic being more advanced, lasts longer, thus less changes required. This is good news to us as we could be doing upto 20,000 a year.

I ordered from Tesco direct yesterday 4 x http://direct.tesco.com/q/R.200-5166.aspx and it arrived lunch time today :shock: ordered on standard free delivery. Not bad seeing i'm up in the Highlands. Hats off to them!

20k miles a year - phew you are travelling. Better get on the veg oil quick. I cant believe the oils have improved by that much since the mid 90s. I reckon the Bongo diesel (with its high compression head?) gives the oil a hammering. Best to change it regularly (may risk 5k intervals with Magnatec if I had to make a guess, but no more). What do the BF soothsayers have to say?

what about going on to synthetic......

It seems to me, once an engine has been on it, it does not like going back to dino oils......

Anyone any views on this?

Hi Mike,
I don't think the Bongo is any higher compression than any other diesel, it's just that all diesels use much higher compression than petrol engines.

I am not an expert on oils, so I wouldn't know how much they have improved in the last 10 years, but I'm sure the other Colin on here would.

I do a high mileage a year too (25k - 30k), but fortunately for my Bongo most of it is in other vehicles. At least someone else is paying for the fuel and maintenance. :lol: I do wish my works van was as nice to drive as my Bongo though.

Hi Lez, what reasons do you have for thinking 'once an engine has been on it, (synthetic) it does not like going back to dino oils......
