I'm sorry I do not write French. I'm doing the Saviem TP3 reconstruction and after 10 months working on caroserie and electricity I'm going for the first long ride (300km) I need to replace the motor oil. The current is 14 years old. Jaký typ mám zvolit? In documentation i see 20W-40 for temp above -5°C. Is possible use oil 10W-40? What are you using? Thanks for the answers.
I'm apologise for a delay. Thanks for the anwers. The side door is probably the modification of a car importer to Czechoslovakia in 1971. The car was used for a mobile computer at the research institute of agricultural technology. He rode alongside the machine in the field and recorded the data.
In TP3 is many other changes from importer. In the spring I will make more photos. I have one more TP3 for spare parts, I'll take a picture here too.
