Good evening

 

The cold months are with us and the time for some routine maintenance (otherwise known as quality time) has arrived

 

My question is this;

Given that my car has modern bottom end shells, modern, little end bearings, 2002 camshaft, pistons and rings & replacement oil pump amongst other things (in fact, rebuilds and replacement parts mean that the head and block are probably the only original or pre 1998 components left of the 1975 engine that rolled out of the factory), which engine oil should I use?

 

Do I stick with the specialist Castrol / Penrite / Miller classic oils?

 

Given that the engine parts are all of modern manufacture, can I utilise a modern multigrade mineral or synthetic oil?

 

Thanks in advance

I have used Penrite 20w60 in my road TR6 for 13 years with excellent results and am also using it in my competition 6 which has a highly tuned engine. This oil, now branded as "Triumph Classic" can be ordered from the Register Office at a special price to members.

I always use Halfords classic 20/50. It's the correct multigrade viscosity spec, contains the necessary ZDDP anti friction additive for classic engines, and it's cheap too. It's blended by Comma, so there's a reputable lubricant supplier producing it.

Basically you haven't changed the engine you have just rebuilt it. You could use any oil, for many years I used detergent (diesel) oil in all my petrol engine cars as did my brother in law without any problems. The one reason for using classic oils is that they have ZDDP in them (hopefully) which you need to protect the camshaft. A local haulier never changed his oil in any of his fleet and they all did over 200,000 when he traded them in! But I do change my engine oil and filter every year with Halfords classic.

The type of oil is more down to the engine design and tolerances rather than the parts used in their rebuild.

Stick to 20/50 classic.

Question comprehensively answered I think!

Based on availability, when I do the oil change it will be Halfords classic 20/50

 

Just have to do the oil and filter, check the brakes (diff and gearbox oil done 3 months ago) and take the delivery module off, so that I can change the fuel supply lines to the injectors, all easy stuff. Should I have said that?

I assume the 'delivery module' to which you refer is the Metering Unit'. Well worth checking here if you haven't done before. Its not difficult but there are things to be done to replace it as you'll have to remove to do the injector leads.

Many thanks for the concern.

 

I had to remove the metering unit back in May, so that Neil F could sort it out for me.

 

I had problems with fuel flow once I had refitted it and Neil was extremely helpful with tips and advice on how to get the fuel flow running again.

 

Having followed his advice, I realised that nature could help, and left the car for 2 days, to allow any air to migrate to the high points in the system. I then followed Neils advice one more time and bingo, 6 cylinders!

 

The current fuel lines to the injectors are untidy, my fault, I was in a hurry to get the car out in the sunshine.

 

Having said that, a bit of quality time, in a warm garage (I plan to carpet said garage this week, to keep my toes warm) with the radio going in the background, what more could you ask?

Back to the oil theme....

 

I normally buy Valvoline VR1 from Eurocarparts, they seem to have a perpetual sale and the price is under £30.

 

However my weekend 'click and collect' order resulted in an email saying they were out of stock :-(

 

I'd like to stick with VR1, can anyone recommend a retailer with a decent price?

 

or should I go with Halfords Classic instead??

Hi Steve, as Jim & TRtom have stated previously. Penrite 20w60 now branded as "Triumph Classic" can be ordered from the TR Register Shop at a special price to members for £27.00 inc Vat & Delivery and it was delivered very quick, within a day or so.

Thanks Kevo.

 

Think I'll order a couple of those then :-)

 

Another reason why the TR Register is such a great club/forum!

Halfords Classic Oil

 

Was £15 for 5 litres last week had no issues & I drive it hard when possible, several trips abroad down to South of France, Le Mans & Spa at speed. :o

 

Cheers

Hi Guys. I’ve just come across this post. Because I’m in the process of oil and filter changing on my 1972 UK PI version TR6. previous posts have mentioned Halfords Classic 20/50. When I clicked on the Halfords website and typed in the above mentioned brand of oil. It asked for my registration number. And when I entered it. It responded by saying Not suitable for my vehicle? I’m baffled. Please advise.

Hi Dave,

 the Halfords classic oil is adequate but can easily be improved upon.

Heritage Oils at Bicester do a very good classic oil  HERE

They can post it to you.

You need a good level of ZDDP in the oil to protect the cam lobe/tappet faces.

Halfords = 800ppm   a bit low

Heritage = 1300ppm as Zinc much better.
